of coarse they will still sell it in the US. if the people in the US spend there money on ridiculous things like the "snuggie" then they will also spend it on the PSP go.
I wish microsoft would get into the handheld business. My personal dream would be fulfilled if Nvidia went into the handheld market. That would be epic. I would greatly enjoy watching a handheld system own the xbox 360 and ps3 in terms of graphics hardware. There's no way that Nvidia would do that though.
