Thanks for that sinha :) So we would have a total of (November+December NPD sales):
Wii - 3,000,000 - 4,500,000 (limited by supply)
360 - 2,100,000 - 3,000,000
PS3 - 750,000 - 1,050,000
These numbers seem to fall in line with TheSource/Siren's estimations, as far as I remember.
My Mario Kart Wii friend code: 2707-1866-0957
