well, i hope they do, because R* must put a lot of their blood and sweats into this game, i would never be more sadder(well, maybe i'll be) if it's a dud, but, i don't think it does, i have faith in them, i hope they release some big news!
honestly, i think R* will have a monster headache if they don't release something before GTA IV, i mean, a budget is needed if they want to delay the deadline, maybe we'll see some releases before GTA IV, that is on the plus side
