I'm worried about the controller as well. I hope they took into consideration that people like me with a short fuse tend to use the controller as a means to vent our frustration, usually in such a way that envolves extreme squeezing and occasionally the "can you make a dent in the wall by throwing this thing" challenge, as the controller is usually the nearest thing to hand when the game cheats and you end up dying for the 30th time.
If they break easily, my controller, if I get teh revolution which as of yet I'm still undecided on how I'm going to decide on getting one (hence my pies vote), will likely suffer extreme consequences within the first few hours of operation.
