Since the game doesn't drop here until Friday I'm less concerned about it than most, but you know what if a game, or games console, is so important in my life that a bit of downtime affects me so dramatically as a lot of people on various forums seem to be, then I'd be questioning my priorities in life.
Either way you get to play Brink, even if it is just offline. The plus side is everyone else on PS3 is in the same boat so no one gets an unfair advantage.
