I'm predicting on old games' sales, as nobody does that. Please quote me and point out my mistakes.
I see something ala
Mario Kart Wii - 4.3M (ending at 13M by the end of the year).
Wii Fit - 5M (ending at 14M by the end of the year).
Brawl: 2M ( ending at 9M )
Galaxy: 2M (ending at 9M ahead of Brawl)
M&S Wii: 1.5M (ending at 7M )
GTA IV combined: 2M (ending at 12.5M)
Halo 3: 1.25-1.75M, at 9.5-10M by the end of the year)
