System:
The Dashboard will have a COMPLETE overhaul this fall, incorporating Mii-like "avatars" that you can customize and dress up and such. New nifty "live party" functions, online XBL gameshows where you can win new prizes, media sharing, etc. I have no problems with the current interface, but it is a little surprising to see them shake it up so much.
NETFLIX!!! You can watch your instant queue on the Xbox, and even sync up with your live party and watch together online. Pretty tits.
Games:
Live demos of Fallout 3, Resident Evil 5, Fable 2, Gears of War 2. All look pretty excellent, and my excitement for them falls in pretty much that order. Seriously, Fallout 3 looks INCREDIBLE.
Rockband 2 will have 84 master tracks on the disc, and 20 additional songs as FREE DLC later this year... apparently they didn't have time to get them on the disc. THIS is how you make fans, Activision. Guitar Who-ro? IGN has the entire Rockband 2 track list... and fuck me, it is amazing.
Lips, a new karaoke game with a flashy, light-up motion-sensitive mic... and you can use your own music. Made by the guys who did Gitaroo Man and Oenden.... if I didn't want this anyway, the wife would demand it.
FINAL FANTASY XIII... and on launch day, no less. I hope you have some healing salve for that asshole, Sony.
Good times, in my opinion. Nothing that I would call mind-blowing (aside from Final Fantasy, maybe), but I am soooo stoked for the Netflix thing, it is not even funny. Tune in tomorrow for Nintendo... and maybe Sony if it doesn't bore me to tears... [/fanboy]
