I'm thinking Kojima will announce MGS 5 after he assissts Sony with the official confirmation of MGS on PSN and that creepy mask project for PSP.

What I want from Sony are some new IPs - I'm annoyed about hearing Heavy Rain, GOW III, Gran Turismo 5 again and again - As a PS3 only-owner and a fan of it I just want something that wasn't announced two years ago and is still having its release date put back - I'm worried that Sony isn't able to produce games for both PSP and PS3 - Sony may have the largest amount of first party studio and the largest amount of second party studios I'm still not sure they can support both - I believe that if Sony focused everything on PS3 then their would be so many PS3 exclusives, Microsoft wouldn't be able to compete

They better have something to rival the MGS MS announcement i tell ya!

Twisted Metal, Kingdom Hearts 3, Kojima's (other) new game and Rockstar's new game are my predictions for Sony. And a couple of new IP's too.

I wonder if there going to show the 3d movies with the glasses i read about a couple of months ago

Jaffe said he wouldn't show anything at E3 this year, so Twisted Metal probably wont show up

Well Sony claimed this to be their biggest E3 ever so they should have more bigger things to announce then what was already leaked.

We'll see. If Sony want Twisted Metal to be a surprise, that's exactly what Jaffe would say.

GT and Little Big Planet Trailers for PSP
maybe some new GT5 trailers and release dates
the MEGATON announcement (maybe the Take2 exclusive)
