Those stats are a bit pointless, it completely misses the PS3 and Wii's 2009 fall sales, and thus gives the Xbox a massive advantage over them. Also, the 360 sales look a bit hopeful, and are unverified. The same with the PSP (quite how an iPhone is defined as a gaming device, im not entirely sure).
