As it stands the Wii is 4,527,314 ahead
Last week 360 outsold Wii by 34,316 so at this rate it would take it 132 weeks to catch it up.
So what do you think? Can it do it or will the Wii hold on?
I also asked this question about 18 months ago: http://gamrconnect.vgchartz.com/thread.php?id=125071&page=1 when the Wii was over 10 million ahead and most people thought the 360 had no chance.
I think the 360 will do it.
