As for games they had Call of Duty: Black Ops, Halo: Reach, Fable III, and... uh... yeah. I think there was a Crytek developed 300-like thing as well, but not sure what exactly that was.
Most of the time went to their Kinect (Connect), which is basically an improved copy of what the Wii has been doing. As a tech, I'd say it's impressive, but it's not really how I envision using an interface or play games. In short: It's useless to me (from what their demo showed). Also, they dared to put 10 minutes of sports (ESPN) in my gaming expo. I guess that's only for the US.
The new console looked nice, and hoping that it doesn't have any red rings, I'd want one.
