Nintendo have a strong line-up but the OP is way off..
Wii works off the back of momentum of which next year it will be coming off the back of Wii Sports Resort, Wii Fit Plus and New Super Mario Bros. Wii.. They'll be the big charting titles for much of the first half of 2010 and beyond.
Next year we'll begin to see a steady stream of third party titles using Wii MotionPlus and of course a steady stream of Nintendo titles including Metroid: Other M, Super Mario Galaxy 2, Wii Vitality and most likely a new IP from Retro Studios and a new title from EAD, perhaps Art Academy or something similar.. Zelda Wii is a 2011 title, along with Project Sora's new IP, Next Level Games next title, Monster Games next title etc..
It'll be a good year next year but the Wii business doesn't operate in the way you've stated, there's a method to the madness believe it or not..
