I don't want to know too much about the game. Hope to see the first boss though. They filed a patent about dynamic level, so this game should be puzzle heavy. Would be interesting if Ueto adds combat elements at the same time (so we have to think fast ;-))
I keep thinking about the Kronos level on GOW3 and i keep imagining what Team Ico will do... Brings a tear to my eye. They did the 'big boss-moving level' on previous generation hardware. They did effects that were 'impossible' to do on PS2.
I can't even begin to imagine what they'll do on PS3, because i'm sure that the trailer shows very little about the later stages of the game, which will be epic...
