Gaahh! are people not reading what i put, first of all, Zucas, it doesn't matter what game goes where it will be the last full week before christmas day that gets the highest weekof sales.
PSP does have a chance, but not a likely chance...last year was only 680k and the year before that was 800k (higher demand then)...both of those weeks had christmas eve and the day before it (23rd) included in the sales...this year doesnt have christmas eve included, and for America neither is the 23rd.
PS2 i seriously doubt as well.
Lets see if i can guess the highest weeks,...i want to see how close i can get.
DS - 1550k
Wii - 950k OR 1250k (tricky one, depend on how supply is spread...i put an OR by the way, not a - so if it is in the middle i failed)
PSP - 850k (helped by extra demand than last year but bolstered by the week placement)
360 - 750k
PS3 - 700k
