I think people just need to accept the Wii is not happening again.
That's one of those types of ideas that it lightning in a bottle and happens maybe once every 20-30 years in this business.
That was something you could play for 10 seconds and immediately understand was completely different from existing video game systems and also it was making games for audiences that had no games being made for at all (today that is certainly not the case as Nintendo themselves is running to Apple/Google to access that audience).
Nintendo Switch is basically a much more elegant, functional version of the Wii U concept. No one is going to play that and go "OMFG, this is unlike anything I've ever played in my life ever!!!". There's nothing really that mind blowingly new here, even the form factor by regular people is going to be seen as just "oh ... it's another tablet".
That doesn't mean it can't be a good system, I wouldn't be surprised if the Switch library ends up being better than Wii or Wii U, partly because all of Nintendo's development resources will now be on one system rather than divided into two. It should have no less than two Marios, two Zeldas, a Metroid, Animal Crossing, maybe even two Mario Karts during its life cycle along with more new IP because there's less software redundancy now.
