To Pezus:
I am not sure if they knew the price because now i cannot find that chart. I think the prediction/forecast was based on the fanbase and market share of PS2 and XBOX. But I remember that forecast was made in 2007. (I might be wrong.)
I am not trolling PS3, but I don't agree that people always emphasize the tough start of PS3 and ignore the difficulty for Microsoft to expand their XBOX brand from the ruins.
