Pre-Alpha footage from sony gamers day (Mostly off screen stuff, the last one doesn't seem to be) 5min gameplay, 720p, off screen http://www.gamersyde.com/news_6441_en.html As for the A.I. http://aigamedev.com/site/2008-plan-killzone
Loved the first one. This one looks great as well. Wish I could get a PS3 right now. Just watched the 5 minute video and those graphics look insane. I'd say the best next gen graphics I've seen to date in real time.
I'm not really that excited about this one. Maybe it's because I hated the first one to death. Although, the video quality in this one looks very impressive, but i'm starting to get tired of the black, grey, and, brown video games. Not even really that excited about GOW2 either.
