I'm still split on this possibility. Pokemon, Mario and Sonic, and Zelda obviously are big games, but not near the sales of some of the biggest DS games like main series Pokemon, or New Super Mario Bros. I also think Mario and Sonic might sell less, as the winter games are not as big as the summer Olympics. I also think it is possible that the Pokemon and Zelda games will sell less than their predecessors on the DS just because of being sequels on the same platform. Throw in the fact that I think the PSP games will be more front loaded than the DS games, and in my opinion it could be close this holiday, with it coming down to if big name franchises can sell well on the PSP.
