i think the pricepoint will garuntee that there arent many supply problems. alot of people talk about spending 250 + 50 per game. not as many people will actually put there money where their mouth it. gamegear, lynx, jaguar ... high priced systems just dont do well with the average poor hick.
with gt4 pushed back, mercury coming out next month, acid getting flat reviews ... their is no real LAUNCH game, like say halo on xbox to help it. same problem the DS has, but at least the ds is about half as much and can play gba games that you probably already own.
i mean hell, i wanted a snes so bad, just for super mario world which was the bundled launch title. tetris was the gba's addiction.
consoles today lack a) an included game b) a defining launch title *save halo*
