Seriously, what are you even talking about!? Retake what lead, the worldwide lead? If so, why are you using american numbers?
The 360 has outsould the Wii worldwide 2 weeks, and 2 weeks only: Halo week by 11k; and last week by about 5k (once Japan's numbers are in). It's possible it'll happen again next week, but I doubt it.
Plus the Wii has a 600k lead already, and in 3 weeks Galaxy releases in Japan.
