well i am still not sure, last year DS sales were 1/3rd of the highest week.... but that didn't include either the 24th or 23rd of December like this year does... so it mostly depends on whether any Wii were put on shelves for those two days (The biggest shopping days of the year)
whatever happens I am sure Japan will not drop.... so that is 250k+ there already, and Others sales might not be too bad, even if UK sells no Wii at all for those last two days it would be held up because supply is not extra tight in Germany, Benelux, Spain, Italy and Scandanavia.
America is where it hinges, as I have no idea whether there were any Wii at all there last Sunday/Monday, or whethr any will be there during the week.
I think I may have miscalculated wrong in my last post, because i said Zucas guess would be a low estimate, but I meant it to be 550k as the minimum, not 650k (Zucas having 675).... which means that i was 100k high saying 750k as well. So maybe Zucas will be closest on the last week too.
