I didn't hate Mirrors edge, but why now? If there was enough support or interest shouldn't they have tried to capitalize on it some tme in the last 6 years?
Releasing it during the mid to late point of this current gen would have just caused the game to be overlooked; it would have been competing against the various other more popular ("AAA") 3rd party games.
Releasing during the early part of next gen would be better... there will be fewer games available for the system(s). Therefore, the game will get more attention as well as more people willing to try it out. If it does decent, the game may end up getting more sequels for the rest of the upcoming gen.
Anyway, GREAT NEWS!
