Nintendo maintains a 'toy' concept of games (even adults like their toys) whereas most game developers these days are trying to make their games into a movie-esque experience and generally targeting an adult audience. If it's not a game you would play with your little kids, he's in no way interested in making it.
Now Tearaway is a cool family-friendly game but aside from the novel use of Vita's various controls it's a pretty generic platformer with a great aesthetic. If Nintendo did make this, it'd be a Kirby game no doubt and then we'd all be complaining Nintendo doesn't do anything new.
I'm mindful that last gen he helped develop Wii Sports, Wii Fit, Wii Music, Nintendogs, Brain Age, etc., which were all far more innovative than something like Tearaway. And yes, the fan demanded and always great selling Marios, Zeldas, DK, Metroids, Kirby's, etc., etc. As far as something truly innovative like Wii Sports/Wii Fit/ Wii Music (yes it sucked but it was innovative) then yes I can see him making this statement, and the innovative stuff MS is doing with Quantum Break, well, that's just not Nintendo's style, strength or desire to make such a thing.
However, people are right to say put-up or shut-up because I haven't seen anything innovative out of him since Wii Music. It's been all rehashes of what Nintendo's done before. And that, is largely is what is crippling 3DS, WiiU sales.
