New Metal Gear Solid gets revelaed.

Agent.

Bioware announces new Mass Effect game at Microsofts press conference.

doubt it on metal gear. with revenge delayed till next year i doubt they will add another one just yet.but i hope im wrong.

Why would Diablo be exclusive to the PS3? As cool as it would be to play it at all, is there an actual reason? Or just a "wouldn't this be bizarro awesome" thoughts?

Dawnguard is announced to drop at the 2110th of July exclusive to Xbox for 30 days(there is going to be a beta)

Agent.

As much as I think diablo 3 will be a console game, I don't know if they care about E3 or exclusivity. 
 
I thought Dawnguard would be later than that, like July.
 
Hopefully on MGS.  MGS4 was 08.  It's way due. 
 
I don't think Agent exists if it doesn't show up today. 
 
Doubt on Bioware.  Dragon Age 3 maybe?  Probably not.  With juuust finishing mass effect and kotor it seems soon.

It showed up on some german online retailer. Other than that though, I think they'd have a tough time getting Microsoft to allow Battle.net, Auction House and (hopefully) cross platform play. We'll see.

BioWare shouldn't announce a new game, that'll just make people mad.

Mass Effect would probably be announced at the EA confrence.

Diablo III being console exclusive to PS3 would be because Sony allows games to communicate with services outside of Xbox Live (As seen with Portal 2 and Steam). Microsoft is completely unwilling to entertain this possibility.

I would expect any Bioware news to be at EA's event, Mass Effect hasn't been an Xbox property since ME1.

I don't think any of those things will happen at all.

Why would Blizzard put Diablo 3 on just the PS3.

Bethesda is having beta testing for the Dawnguard soon so why would they release the full expansion in like 17 days.

They haven't even finished the Metal Gear game that is being worked on.

I have no reason to believe that Agent is still being worked on since they haven't shown or done anything for several years (plus GTA V).

If Bioware was going to announce a new Mass Effect game it would be at the EA press conference but I don't think they will announce another Mass Effect game this close to the end of the "trilogy" unless they want to piss even more angry fans off.

Why would Diablo 3 need cross platform communication? I can see it being announced for consoles, maybe even at Sony's conference is a huge bombshell.. But there's no reason it'd be exclusive, they can make too much money by bringing it to the 360 and Wii U as well. Besides that, I'd say a "shoe-in announcement" is for Microsoft to announce they're launching cross-platform music/video services and maybe even expanding their games to new devices, like what they tried with Zune.

Mass Effect/Bioware news being at Microsoft's conference isn't very unlikely either, MS often have third party stuff on show. They even made a big deal out of Mass Effect 3 last year, remember that big demo?

I doubt Bioware will say anything about Mass Effect I mean technically they haven't even finish ME3 (extended cut) , maybe something about Dragon Age 3 a trailer/teaser or C&C Generals 2 but that isn't 'Bioware' .

I'll wager we're going to see more of Fortnite.
