Lets see - 3/8 weeks will be after the Xbox360 Arcade price cut, I consider those weeks will have the Xbox360 ahead of the PS3 for sure.
This week I expect the Xbox360 will have another winner off the back of strong sales in Japan. The week after is Madden week, so I would say its all looking pretty good for another Xbox360 win.
Thats 5/8 weeks, the other 3 I can't account for. So i'll just leave it to fate.
Tease.
