Game Trailers has a couple of walkthrough vids of the upcoming Ico/Shadow of the Colossus HD remakes and they are both looking incredible. Personally, since I always felt that Shadow of the Colossus was just a step too far for the PS2 hardware, I can't wait to replay one of my favourite games of all time with a solid framerate!
The above video takes an in-depth look at Shadow of the Colossus, and below we get a look at the HD remake of Ico.
Shadow of the Colossus, in particular I think, is looking pretty incredible.
