I missed almost an hour of the show but I'm still quite satisfied with the stuff I saw.
I'm quite stunned how many new features 360 is gonna have with all of those last.fm, twitter and facebook stuff. It's also gonna be great to be able to rent some movies here in Finland (the current thing isn't available over here).
The real time motion capture stuff looked nice also, though I kinda hate those casual Wii games so I'm not that excited about it really, hehe. I think Sports and Extreme Sports games will really benefit that feature if it works well enough. As long as the motions won't lag too far behind.
Oh and I've been waiting quite long time to see more of Alan Wake and was really satisfied with the short demo they showed, Remedy is a local game house after all ^^. Oh yeah and Metal Gear should be quite cool also, not a fan really but the games are definitely worth a play.
Gonna add some more impressions when I check the rest of the press conference ^^
