Every Christmas seems to have one game that the reviewers despise that moves massive units. Last year it was Nerf N-Strike. The graphs look pretty similar, so far:
http://www.vgchartz.com/swlaunch.php?reg1=All&game1=NERF+N-Strike+-+Wii[25319]®2=All&game2=Just+Dance+-+Wii[40053]®3=All&game3=&weeks=60&weekly=1
Just Dance was released closer to the holiday spike, and it's doing it mostly in EU, while N-strike did it all in NA. If the pattern holds, Just Dance could sell ~100k for another 2 weeks, then tail off to sell ~10k for another ten weeks. So somewhere over 500k by the end of the holiday season, and close to a million this time next year.
