The top ten probably won't look too different from now actually, its just the new COD will replace the old COD and some of the positioning will change. I do think this is the "Guitar Hero 3" Christmas for the dance games though - Just Dance 3 and/or Zumba Fitness 2 and/or Dance Central 2 - maybe all three will be up explosively on their previous iterations. Twilight Princess actually did around 7.5m (Wii & GC) - of which 2.3m sold in 2006, which is pretty good on the ~25m base the nearly dead GC and still tiny Wii had combined. The Wii base is nearly four times larger than the GC & Wii base combined in 2006, so you'd expect a much larger uptake everywhere but Japan where Zelda isn't that popular now.
The big games by platform in the West for the remainder of the year are essentially:
Wii: Zelda, Kirby, Rayman, Mario Party 9, Just Dance 3, Zumba Fitness 2, Black Eyed Peas, Mario & Sonic, COD, Fortune Street, Lego Harry Potter, Spyro
PS3: Uncharted 3, COD, Battlefield, Skyrim, Batman, Sonic Generations, Ratchet & Clank, Rayman, Assassin's Creed, Fifa, Madden, PES, Need for Speed, NBA 2k, Just Dance 3, Max Payne 3, Ace Combat
X360: Halo Remake, Gears of War, COD, Skyrim, Battlefield, Batman, Assassin's Creed, Forza, Rayman, Sonic Generations, Kinect Sports 2, Dance Central 2, Need for Speed, Blackeyed Peas, NBA 2k, Fifa, Madden, PES, Just Dance 3, Max Payne 3, Ace Combat
3DS: Mario Kart 7, Mario 3D, Spyro, Shinobi, Ace Combat...
Not a particularly great year if you dislike shooters, platformers, and dance games - those should be the big winners over Christmas though. The volume of good to excellent platformers (Rayman, Shinobi, Spyro, Mario, Ratchet, Kirby, Sonic - and its not like the previous Wii platformers will be dead either) this holiday season is pretty amazing though. Same goes for dancing games and shooting games.
