Gee, I remember thinking the Gamecube had pretty odd controls when it came out. The C-stick seemed like an odd compromise between the N64's C buttons and the PS 2 controller's dual analog sticks.
The problem is that everyone wants to create bold new interfaces, but few people want to refine existing ones. If you can make a breakthrough, go for it, but if not... just make iterative improvements. I'm a lot happier with how Sony and MS have gone with their controllers, by contrast.
Honestly the Switch seems like the closest thing to a classic control scheme that they've had in a while. If it had more than 3 hours battery life, and didn't seem in need of a day-0 patch, it might even be worth it.
Both the Wii and WiiU offered pretty good controllers so you can do just that.
The Switch, however, will be the first console I'll buy. I'm not too happy with the low specs, but it's somewhat justified by the portability. And if Nintendo does what I hope they'll do, I'll be able to play a whole bunch of older and indie games now that there's a normal controller as a default (portable Metroid Prime!?!).
Unfortunately I don't quite trust Nintendo to be sensible, so I'll have to wait and see what happens first. I'm very tempted to get a second-hand Wii U so I can play Zelda and go through my unplayed first-party back-log, though.
