The numbers you give at the top are only for the US, in Eu the 360 only sold more for the Halo release week, and WW Halo week 360 only managed 11k more than Wii, with this week looking like it will roughly the same, possibly a bit less.
---------------------------
If the Wii had absolutely no extra supply over Christmas it would sell over 15 million.
The best the 360 can do by the end of this year would still be about 15 million (that's keeping up with Wii until the end of the year)
however it is confirmed there will be an unprecedented supply of christmas Wiis, and that definately amounts to no less than 16 million (tbh unprecedanted meaning only 1M extra is being really pessimistic). The 360 can not manage that.
Worst case scenario for Wii, best for 360 would be a mere 1 million console gap by the end of 07....i'm expecting more like 3 million.
