I share all of your concerns regarding framerate, but I can't recall Nintendo being lazy on performance. Most of their games have always worked flawlessly, except for few irks here and there (WWHD and explosions, Pokemon). With 6-7 months until release, I'm pretty confident they will improve it vastly, both for the Wii U version and the Switch one
