Oh, and be sure to follow me here on Giant Bomb for the latest updates on these contests!

So what do you have to do to enter, just write in this thread?

I will be interested to see if PC get's any kind of floor time this year, what with Microsoft recently claiming that they are focusing on PC and all that again. Honestly though, I'm sure it will get as much attention as it did the last dozen times Microsoft said that too. None.
Will be curious to hear about this Wii 2 thing too. I have been purposely avoiding any of the rumours about it, so I can give Nintendo their best shot to shock and amaze me with it's unveiling.

Other then that, it's always about the games. Out side of a handful of games coming out from people that would never in a million years have the chance to sell their games to people at E3, I can't really think of anything that's coming out in the last half of the year that looked interesting to me. So I get the feeling that this event will make or brake my excitement for this year of games.

I'm looking forward to Nintendo's announcement of a new home console at E3. I'm rather stoked about it actually. Should be a hoot. If all the rumors are to be believed.

I'm looking forward to some new game announcements.  Stuff like Shadow Complex 2, GTA 5, Half-Life 3.  A new non-Kinect Rare game, maybe? Okay, Shadow Complex 2 is the only one of those that might happen but I can still hope.  Also looking forward to Codename Kingdoms footage. 

" @Meltac: Yep! Just follow what the "How to Play" section says to be eligible! "

I'll probably be disappointed yet again but I'm still waiting to see The Last Guardian fully playable. It is my most anticipated game of whatever year it decides to come out. :P

I need to know more about Skyrim!

I'm most looking forward to seeing if Nintendo really does reveal their next console.

To be honest I'm looking forward to the New Developments in Kinect for the Xbox 360. As somebody who has purchased Kinect I was kinda disappointed at the amount of games that have been released for it since its release last year, there weren't very many and if they were not aimed at young children they were all about fitness and I can tell ya, I ain't one for fitness! I'm just hoping they release so games for the casual/hardcore games market that aren't amazing by things such as "Kinectimals", I a decent fighting game, maybe even a shooter!

i'm most excited for this year of E3 is, what nintendo's new console is going to be and even if it's going to be a entirely new console instead of an upgrade.

It would be awesome too see GTA 5, Shadow Complex 2 and Half Life Episode 3 get announced as well as see some more of Saints Row 3, Rage, Mass Effect 3 and Uncharted 3. 

I'm most looking forward to things we haven't had announcements for (or leaked info) yet.

Here's hoping we see Doom 4 this E3.

I'm very very excited to see if Microsoft and/or Sony will reveal a new console. I love my X360, but I also feel it's due for a new generation leap.

When it comes to games I'd die a happy man if I'd see any of the following titles announced for the X360 (except the MMO obviously):
Just Cause 3
A new Culdcept (released in EU this time as well)
A new Katamari
Condemned 3
Something new from Rare that's not linked to Kinect (a new Banjo-Kazooie maybe?)
Dark Cloud 3
A new Tales game
Borderlands 2
More info on Blizzard's next MMO
Plants vs. Zombies 2
A new Peggle
Shadow Complex 2

The list can go on and on, but that's just what springs to mind right now. :)

RE6, some XIII-2 news, new Sega console.

Oh and killing floor if I win please lol.

Anything new from Level-5 that doesn't involve top hats and critical thinking (I'm still one or two Layton games behind) or poor-ass Monster Hunter knock-offs (hi White Knight Chronicles). Seconding @CrazyChris: 's Dark Cloud 3 suggestion. Fantasy Life sounds kind of neat too. Honestly, I don't follow E3. I'll get hyped for a game once it's out and the Quick Looks start showing up.

I'm hoping for some kind of mind blowing announcement that nobody is expecting.

Splinter Cell Double Agent or Cogs on steam would be awesome, steam name is blaze503. I only have a pc, this is really cool btw.

It would be cool to see what is possible in the next series of consoles they may announce, even though I won't be able to afford one lol

I just want Nintendo to announce a follow-up to the Wii. Get on with it, already!

I am most looking forward to hearing about something awesome that I had never thought of before (You know, like Portal was back in the day). I don't expect to get that, but it does happen occasionally.

I want Enslaved quite a bit.

E3 this year is going to offer a lot of info about games that I desperately want to play, but because they will come out later this year there will be plenty of coverage of Mass Effect 3, Skyrim, Arkham City, and a few more highly anticipated games. What I'm really hoping for is to finally see an official release date for Diablo 3.

" I'm looking forward to Nintendo's announcement of a new home console at E3. I'm rather stoked about it actually. Should be a hoot. If all the rumors are to be believed. "

hopefully a valve announcement about episode 3 or DOTA 2.

I'm most excited about what Nintendo has to announce, whether it be the rumored console or just new games.

I'm most looking forward to whatever Microsoft has to reveal. I play my Xbox a lot, so sue me.  =P

The idea of a new Nintendo console has me interested in seeing what they do. I haven't owned one of their consoles since the SNES, but I if they're moving ahead before MS and Sony that may change. I'm also hoping for some good ME3 footage, I can't wait for that game. It's my 2nd most anticipated game of this year, but with Portal 2 being my first, it's only hours away from getting a bump.

I am looking forward to E3 this year, more so than any other year.  It definitely has the potential to be one of the best.  Here's what I'm looking forward to/hoping to see:

C'mon random line picker... pick me!

EDIT: Also I'm most excited to see if this mysterious "Wii HD" is actually a thing.

I'm hoping for a half life 3 announcement

I'm looking forward to Respawn and Bungie both independently announcing their own visionary new fpsmmo projects that will not wind up being very good.

Enslaved

I'm most excited to see what games are coming, and release dates for the games I'm most excited about.  I guess of all the three consoles, I'm most excited to see what Microsoft has lined up for the foreseeable future.

would like to see info on a new Rainbow Six and Resident Evil...really hoping to hear something about Half-Life

At this years E3 I'm really looking forward to seeing more from Mass Effect 3, Saints Row 3, Max Payne 3, Diablo 3 and Battlefield 3's multiplayer. 3.

A copy of L4D2 would be great, if I were to be chosen!

i want to see this magic "super wii".

I'm looking forward to more NGP info and hopefully a price tag. 

Nintendo has a new console announcement. I'm pretty interested in what that will be
I really hope I get Enslaved.

I'm always eager to see if Valve has any surprise announcements (you know the one).

I'm also curious to see what's up with the rumored Nintendo hardware.

I'm mostly looking forward to the stuff that always seem to come out of nowhere and surprise me..!

If Project Cafe is going to happen, I am incredibly excited to see that. Otherwise, just new 3DS games (like that Mario platformer one) and new NGP announcements/footage.

I also want new info about Zelda SS and Skyrim, so I can completely tear it apart because they've ruined everything. But hopefully not.

I'd very much like for Nintendo to announce their home platform to compete with the iPhone, Android, and tablet market that goes for simplified interface and controls with complex challenges in other places.

I'm looking forward to Nintendo's console announcement. Curious about what game(s) they might show off for it. Also that Wii Kirby game. What's up with it?

It wouldn't take much to make me happy, just hearing something about Mass Effect 3 would do it...
That and winning Left 4 Dead 2 ;)

I'm definitely looking forward to the announcement of a surprising new IP :o

I want to see some more Skyrim, and also see some of that Wii 2 craziness.

I guess I wouldn't mind Audiosurf.
