Who ever thinks Sony is winning in the handheld race is an idiot. Keep in mind Nintendo has 3 Handhelds out (4 in Japan). Currently in Japan, Nintendo outsells PSP at about a 5 to 1 ratio. In the States, PSP is selling well. When compared to GBA and DS sales combined, not so well anymore. And on a global stand point, PSP is getting raped. And no, its not gaining momentum, if anything its losing momentum. So where ever you read that, I beg you to show me... and I'll show you where I read its losing momentum.
Nintendo owns the handheld market, and it always will, PSP WILL fail, not right now... but it will. PSP will not be around in 2010, not a second version, or third, none at all. I'm not saying that cause I'm a Nintendo fan or anything... software-wise, psp blows. It is getting a bit better, but Nintendo on a software stand point, is blowing PSP away. Just check the games sold stats.
