IMDB says release date for the USA is 11 June. One commentor says that he got a first view at the movie and that it looks very good; of course, that's just internet info.
Edit: I'm giving a quick look at their messageboards, and there's a guy who says that Vin Diesel owns the company who is making the game based on this movie. The guy is a successful actor, plays D&D, and owns a videogame company? I think that only lack of sleep prevents me from blowing up in envy. >_<
