Ok, saw the 3 trailers and look for more info on the games and...
Until Dawn, looks very raw, models and animations look very stiff, setting is interesting but developer does not have any great games in their profile, at least it has Move experience. Good idea, will wait for implementation.
Rain, very interesting concept, not sure how it will play or what the character does, seems very promising, but a little more than a conceptual idea, PSN launch can allow to explore possibilities with low risk, the most interesting for me.
Puppeteer, the most advanced of the 3 games shown and seems fun, plataforming with a little action. World design looks very good, mechanics solid, physics well developed, not my kind of game but a very good addition to the PS3 lineup.
