These are the first week number for RB3 in the UK:
5318 Xbox 360 copies, 1555 PS3 copies and 295 Wii copies.
This is terrible by any measure. I was actually looking forward to this game but I might wait because prices are going to fall like a rock after the holidays. I could see stores being stuck with tons on inventory for instruments.
Anyone can guess. It takes no effort to throw out lots of predictions and have some of them be correct. You are not and wiser or better for having your guesses be right. Even a blind man can hit the bullseye.
