You talk about the playstation name which should sell consoles. What about the fact its the first attempt at a handheld for Sony, and this is Nintendo's third crack at handheld (and the first 2 did awesome)??
Playstation is a huge name in home consoles. But Gameboy/Nintendo is the name in Handheld gaming. How about 40 million sales in what 4 or 5 years? Not bad at all.
