This is the new footage that popping up on the internet right now that comes from Playstation Lifestyle. They claim that it's Trico, the newest game from the developers at Team ICO and the footage looks pretty darn convincing to me.
The game seems to center around a young boy and a creature that looks like a griffin or a bird/dog thing. The graphics are pretty stunning for something that's coming through on you tube. Hopefully we'll know more when E3 starts.
