Just linking to a few sites' E3 index for those who just want to have a quick glance at what games are mentioned/introduced.

Noting a few things:
Metal Gear Solid: Rising will be 360 exclusive.
Dead Rising 2 is coming out on PS3 and 360.
Assassin's Creed 2, sequel to a game that I loathe, is coming out on PC, PS3 and 360.

Sony has dated God of War 3, and Bandai Namco is annoucing this.
Then Ninja Gaiden Sigma 2 is announced for the PS3.

I haven't had the chance to look at the trailers yet, but it looks like a pretty good convention so far.
