Last year's Numbers comparison:
November 2006 NPD
Wii 476k (supply constrained launch)
PS3 197k (supply constrained launch)
VGChartz Hardware data for the period 12th Nov 2006 to 03rd Dec 2006 (America):
Why the difference is so big? Even after adding 10% for Canada the difference is still 30-50% for this gen consoles.
I think that may be a consequence of NPDs irritating method of allocating weeks into months.... Rol said that December is always 5 weeks for NPD, and Jan 2007 was unusually a 5 week for NPD too...... I assume the December 2006 NPD 5 weeks ended on the 31st of December, meaning that the week ending the 3rd December was included into December NPD.
Basically last years November NPD was in fact almost a week earlier than this years.... and so we should compare with these VGC numbers:
VGChartz Hardware data for the period 05th Nov 2006 to 26th Nov 2006:
so in fact they are very close. (we could take 10% from VGC to account for Canada, but as it is November, with Thanksgiving it is usually less than 10% as i have just seen the Canadian NPD numbers for this November)
