We all know the NPD data for december: 360 - 4.5 Wii - 1.1 PS3 - 0.69 According to the first page: 360 - 5.14 which is 4.5+14% Wii - 1.43 which is 1.1+30% PS3 - 0.91 which is 0.69+32% While 360's 14% looks pretty fair, i dont understand those 30%%. Arent Wii and PS3 numbers overestimated a bit ? (forJanuary,1) On the other hand, if we count 2 weeks of January in, numbers would become underestimated. So can anyone tell me, where did these ~15% come from ?
