While I enjoy Nintendo's main franchises (Mario, Zelda, Metroid) I've never purchased a system for them. Godfather and Dewy's Adventure had as much influence on my buying Wii as Wii Sports and Brawl. Same with DS, I played more 3rd party than 1st on it.
Unlike Wii's motion controls which I loved and still do, WiiU's gamepad is not only not compelling, I find it annoying. The system is barely more powerful than current gen systems and I own a 360 which has all the same (and much more) 3rd party games (except Sonic, etc).
So far 3DS's Nintendo games are very similar to what WiiU has/will have - 2D mario, 3D mario, DKC, Fire Emblem, Mario Kart, even Smash Bros. It costs a lot less and has more 3rd party support. I'm more likely to buy that than WiiU.
I also share your concern with WiiU. I've been predicting it's early demise long before it launched. And once Nintendo starts to focus on a new system the old one is abandoned in it's last year which we've seen again and again. That'd mean 2012 and 2013 would likely be the only 'good' years for Nintendo games on WiiU and considering this years line-up, that's scary.
I'm sure I'll miss some good WiiU games, but I can always catch them later on Wii3 or just enjoy the 3DS versions. Or the Wii versions which I still have a huge backlog on and frankly Mario Kart, Smash Bros and NSMB just don't look much different than they did on Wii so I don't think I'm missing much with WiiU.
