Yeah, he wants it to look even better and is aiming for 60FPS/1080p.
I thought it was funny how everyone said "this is next-gen!" when they saw this. It's not that I disagree with them, I thought it was next-gen too. Just goes to show how masterful Kojima is, and also makes me weary of even considering the next-consoles until at least 2014.
I think you guys will be sorely disappointed when you see the game running on a PS3 or 360.
