The DS sold 5 million in December last year (most of which will have been within the period before christmas, less than 4 weeks.) So yes the DS is a definate. I doubt it will be for 6 weeks in a row (it was only 3 weeks in a row last year)...4 weeks in a row is possible though.
Wii could manage 1 week over 1 million, maybe 2 if there is massive supply (ie 7 million supply for Nov/Dec...i'm guessing 6 million though)
Actually i have just checked the day of the week the 25th is on, it's a Tuesday, so i doubt DS will manage 4 weeks because it wont manage 1 million on christmas eve alone (monday)....although the US charts now end on Saturday, so they get the Sunday and Monday.....hmmm, if christmas had been on a Wednesday or Thursday i'd have said yes to 4 weeks over 1 million....but i doubt it.
