You never see wacky features coming, they just hit you in the face like a flying Wii Remote!
Lockstep with industry? Not sure I agree. We've had Switch that was a whole new category of console that gave Nintendo a specific place in the market, and now we're just assuming they'll stay neatly in that category with the next console.
If Nintendo does stop being weird and innovative with hardware in the long term... I think that would be bad because we won't get more fun new things like Wii, Switch, Virtual Boy, 3DS, etc.
