To be honest the Wii era was kind of a bust for Nintendo fans in a lot of ways.
We were always sold this line that with a big userbase we'd finally have all these great third party games, but the system was so underpowered that it got nothing but crappy spin-off games or a ton of shovelware mini-game titles.
Great for soccer moms or if you wanted a weight loss fad, but not really great if you actually wanted to play quality games.
The best Nintendo games for the system, things like Super Mario Galaxy 1/2, Xenoblade, Super Smash Bros. Brawl, Mario Kart Wii, Donkey Kong Country: Tropical Freeze, NSMBU, Zelda: TP honestly would play just as well/better with a regular controller, and even the aiming in Metroid Prime 3 ... Splatoon has shown you can do that just fine with a regular pad.
So essentially that era ended up with Nintendo fans, most of whom had a GameCube, which was $99 by 2003, paying 2.5x that cost for basically the same hardware slightly upclocked, a piddly amount of on-board storage, with a new controller.
And we got no graphics/hardware update for 6 years, being stuck playing our games in SD resolution when most of us had HDTVs for years.
Honestly there's very little the Wiimote actually brought to the table of a Nintendo fan other than bragging rights on internet forums because Nintendo was selling a lot of product to fickle soccer moms/casuals for a couple of years. It didn't make the games better.
Even the whole "well Nintendo will make so much money off these casual gamers that surely they'll in turn spend that money on awesome new studios, like how they used to have Rare in the past!" ... that turned out to be a bust too as Nintendo barely invested in any new 2nd party studios.
