I don't know if Nintendo will or not. I agree that with the Wii we've seen differentiation weed its way back into console design as a positive thing (whereas if you look at PS3 and 360, or at last generation, you see any deviation from the "standard" by a given party severely frowned upon, like all the complaints about Microsoft using non-standard hard-drives, or GameCube's mini discs, or PS3's GPU), but it'll be very tempting to Nintendo to finally have a console that could exist in today's "multiplat everything" world, where they wouldn't have to fight tooth and nail to get big-name games to come to their platform at all (though then there's the fight to make them exclusive)
Though Nintendo is in the unique position that they could set the standard for next generation, depending on when they release the hardware. So there is merit to what you're saying.
