And expect Nintendo to somehow suddenly make their Mario, Zelda and Pokemon series filled with mature content is just silly. Those games never changed besides graphics and controls, and they never will either. Nintendo been stomping on the same ground regarding their games in the past 25 years now, why should they change? The Wii Fit isn't "new" either, they had a http://www.gamersgraveyard.com/repository/nes/peripherals/images/family-fitness-box-front.jpg, which I enjoyed greatly at my neighbour.
And only late teens and guys in the 20s view the Nintendo console as a "kids console". 30 year olds do not. They aren't afraid of playing fun games like Mario that aren't deemed "cool" because it lack guns and blood.
Kids games are things like Barbie Horse Adventures, and really, how many advlts play those? But advlts play Mario because it's fun.
I'm not sure what you mean with the bandwagon here, but if you're talking about controls like the Wii remote, you have to remember that Nintendo was first the LR buttons, the rumble function and the anologue stick. Microsoft and Sony followed Nintendo on those things too, was that a mistake from their part?
