Just finished watching it, personally I was disapointed at the lack of Monster Hunter, one of my favorite games series. Think it would probably work quite well on the PSVita.
I was also quite supprised at the announcement of a ICO rerelease, I remember playing the demo around the first time I got my PS2 though at the time I was terrible at it. I would be interested in trying it again once it's released.
I also noticed a lot of 3D stuff being done, and the Sony TV thing looked quite interesting, one feature I espcially liked was how two players could do split screen, that takes up the whole of the screen instead of just half. It's a genious use of the 3D TV and will probably make Co-Op more enjoyable. Though the price for the TV and additional glasses is a bit high.
