As the title suggest, what are you excited for?  I'm really pumped for the multiplayer, and the campaign. Not really a fan of Horde Mode, but i will give it a try.

Being able to play as The Cole Train during part of the campaign is really awesome. 

Pretty much all of it.

Dedicated servers, and FINISHING THE FIGHT.

The epic edition..

Taunting my PS3 only friends with it. Telling them how awesome it is and how they are missing out, yo. :D

Not really ill probably be playing dota 2 and RO2 and CSGO and BF3. EPIC MAKE A NEW UNREAL!

Campaign and sweet, sweet horde.

Pretty much everything. 
 
Single player will be great.  4 Player coop and the series finale. 
 
The new horde might be pretty fun, something to do every once in a while, same as Beast. 
 
But the multiplayer, ohhhh the multiplayer.  I'm convinced it's going to be the best multiplayer game i've played in a long time (judging by the beta). 
 
 They're fixing pretty much everything i didn't like about gears 2 multiplayer, and adding so much great stuff.  Rifles will be useful.  There will be a greater variety of weapons and they will be VIABLE in different situations  Anyone can have their own preference and style for spawn weapons.  The host issues and bad lag/bullets not going where you tell them will be gone.  Movement is refined, where you wont be hopping constantly to go faster than simply sprinting.  Meatshields are nerfed.  There are more ways to get kills and more satisfying ways to get kills and humiliate the enemy like punching people in the face for 10+ seconds.  There are executions for every weapon.  The chainsaw is actually useful. Grenades are more balanced. 
 
The beta just blew me away.  But i'm especially looking forward to playing gametypes without respawns.  That was the main thing i didn't get from the beta, because I enjoy the tension of having one life per round and the greater emphasis on strategy that comes from warzone and execution (and I don't like people getting lucky and spawning behind me).
 
I fully anticipate it to be my GOTY and keep me entertained for a looooong time. 

Campaign mostly. I want to know how it ends.

probably horde 2.0 and the Carmine situation.

the story

Multiplayer. They've taken out everything that I didn't like about it before and polished it to perfection, and that was just the beta.

I just hope the multiplayer isn't a joke.

I really hope there's more modes than what the beta gave up, I'm gonna miss the one life rounds.

After playing the beta it's gotta be the multiplayer. It's soo much better than in the first two games.

Fucking everything.

The end of the story. So the campaign I suppose.

Campaign mostly. I want to know how it ends.

Finishing the fight! Never played much of multiplayer in GoW1/2 but I will probably at least try it this time.

Campaign mostly. I want to know how it ends.

Multiplayer I guess. And that bitchin controller .

That it being released means Arkham City is less than a month away.

Whenever it gets cheaper in a month or two so I can buy it for half the price. har har har

Weapon balance and dedicated servers. I need that retro lancer.

Pretty much all of it.

Unreal Tournament IV

Tbh, I'm not excited for Gears 3 at all. Looks like more of the same and I want new experiences. I will probably play it sometime next year or so.

Everything.

I wil jump right into the campaign with my cousin, then Horde and beast mode till we drop.
We had so much fun in Gears 2, this can only be better!

Campaign and Horde #*$@ Competitive multiplayer. 
 
And im still hopin they kill Anya instead of any one else.

I'm am really excited for it, I was so close to getting the epic edition but I really can't afford it, can't wait!!!

I can't wait to hug those chest high walls.

Finishing the campaign is the part I am most looking forward to. I will definitely play a lot of the multiplayer but I am not super excited after playing the beta.

Most excited to see how the story ends, despite the shit people give it, I like the gears universe. Also I spent a lot of time playing Horde in Gears 2 so I'll probably be burning a lot of hours in Horde 2.0.

The campaign.

Horde 2.0 - I love the idea of building fortifications using the money earned from kills. Now, I must say that in every game I own except for a few, the single player campaign ALWAYS takes priority over everything else on the disc. So even though Horde 2.0 wins it, the single player campaign is a cunt hair below Horde 2.0.

More chest-high walls!

Everything,even horde/beast modes for them days when i'm not playing all to well :3

But mostly the MP as gears 2 was one of my most played MP games ever :D.

I'm most interested in the singleplayer because I want to see it through, but I'm looking forward to horde and MP as well.

I really want to play as a Ticker in Beast mode, it seems both creepy and exhilarating.
