Please lets not get stuck in the discussion of what is the definition of "new ip".
I agree, that the immersion of a game changes drastically when it is set in a new universe, but should we limit it to that point when calling a game innovative? Nintendo innovates drastically in gameplay mechanics while sticking to existing franchises. In that piont I completely agree with OP. It is stunning if you think of the range of gameplay Nintendo offers and invented.
Fire Emblem, Animal Crossing, Pikmin, Kid Icarus, Wii Fit, Zelda, Pokemon just to add some to the games OP already mentioned.
