It sold around 200k each week for 6 weeks. I don't think it's going to stop before 5-6 million.

Not any more. It's sold > 200K every week for the last six weeks and matched or exceeded it's launch week twice already. It'll have sold more than half Just Dance sales by the end of the year, and I fully expect it to exceed Just Dance in 2011.

Edit: I'd like to also note that the game is breaking the "sequels always underperform on Wii" rule.

Yep.. I was wrong on this.... good call!

I expect Ubisoft to milk this to death.

I find so hard to believe this game is having this amazing numbers and games like Kirby Epic Yarn and Metroid The Other M pretty much tanked.

800k last week, it's unstopable !

What are your predictions ? 6, 8 or 10 milions lifetime ?
