I love revisiting threads like these. The results so far:
Japan Americas Others Total
Week 1 943,582 952,279 323,419 2,219,280
Week 2 454,233 598,402 343,606 1,396,241
Week 3 549,756 372,520 369,986 1,292,262
Week 4 n/a 477,153 341,344 818,497
Total Japan - 1,947,571
Total Americas - 2,400,354
Total Others - 1,378,355
Total - 5,726,280
Will probably be at least 400k (now 500k) more with complete Japan numbers. So a good estimate would have been 6.1 million after 4 weeks. Given that number, the predictions in order of closeness:
1) haxxiy - -0.6 million
2) Ganondorf7799 - -0.76 million
3 )Green Penguin - -1 million
3) Lucas Rio - -1 million
5) Pineapple - -1.1 million
6) Wii Master - -1.6 million
6) Puffy - -1.6 million
6) blizzid - -1.6 million
9) Buzzi - -2.02 million
10) Snake612 - -2.6 million
11) retroking1981 - -3.6 million
12) kingofwale - -4.2 million
Sorry if I missed anyone or miscalculated anything.
It's sure that however much the game sells in Japan the coming week, the order will stand, because everyone guessed below the current number VGChartz has it at after 4 weeks.
Most people were wrong mostly on Japan. It had a much, much bigger impact there than anyone had anticipated. I think it's now safe to say the game will definitely break 10 million, and that it will outsell galaxy lifetime.
EDIT: It seems now that the game sold 500k last week in Japan.
