Well it's a Kinect game but what about Project Draco?

Left4dead and Halo Wars are my guess

XCom isn't exclusive it's on pc too and Codename kingdoms could easy be on pc and/or ps3 aswell, and I can see Xcoms going on ps3 too, not to mention anything new from valve and Draco is a kinect game which he said to excluded, so yeah, TC if you are looking at exclusive, exclusives only then pretty much gears and forza is all you get, if you don't care if it's timed/on pc too, then you have a few more, but no guarantee they are going to be any good, 360 has very few exclusives announced at all let alone for 2011 release 

Lets asume codename kingdom is just 360 and not PC...

Gears 3 (Seen some ingame)
Forza 4 (Just CGI)
Kingdom (..)

Thats the confirmed ones :L

There's plenty of exclusives, are you asking about AAA titles?

O Gawd, other than Gears3 theres basicly nothing....my 360 would have seriously been thrown in the closet if it wasnt for multi- games, Looks like 2011 will be the year I start to build up my ps3 library!!!

Maybe a new Left4Dead, unless its multi-plat because Valve loves the PS3 now. 

I really, really, really hope its not just a year of Kinect shovelware. 

If there's one thing Microsoft is good at it's pulling exclusives out of their ass, especially around E3. Pretty much the following happens every year. Sony has a long list of exclusives, about 20% of which end up getting delayed and Microsoft has only 1 or 2 games for the entire year only to announce 2-3 during E3.

One thing that might change this year though is that Sony list of exclusives is even bigger than usual to the point that even if 20% do get delayed, it's still gonna have over twice as many as Microsoft's. Also, Microsoft is fairly dependent on third-party exclusives. With Mass Effect and likely Left 4 Dead going multiplatform, Microsoft might have be lacking in exclusives if they can't make some new relations. Crytek was a good start, but I wouldn't bet on Codename: Kingdoms making it in 2011.

I'm sure they'll be plenty of random PC/360 that come from nowhere.

Idol Master 2!coming to American&Eurpoe 2011!(wait wat)
