Donkey Kong Country and kirby are guaranteed sales. DK especially enjoys mass market appeal as well as a loyal following. I agree with the general sales accessments made here already on these two.
However this article ignores the true Nintendo IP for the holidays - Wii Party, which should sell 10-20m ltd
Kid Icaris is for all intent and purposes a new IP. It would be a mistake to launch it on Wii at this time. It'd be ignored.
However on 3DS, it is a game that especially benefits from the 3d and highlights it. Also all launch titles on new hardware tend to do well. Look at Luigi's Mansion. Or Wii Sports in Japan (where it was sold not packed in). Partly it's because it's the only thing available. Partly it's because Nintendo's launch titles typically are games that highlight the perks of the new hardware which everyone is excited to try out. I'm sure Kid Icaris will enjoy strong initial sales. Once other major titles hit, it may fade away.
