How Will Nintendo Achieve BC next generation, if they do?

[Frogger]

Whatever "absorbing the Wii U architecture" implies, that's how they'll do it.

But they definitely are keeping BC. That's core to the unified platform.

EDIT: To clarify, I'm only talking about digital BC. Every game available on the eshop now will be playable on the NX at launch. I don't know, nor do I care about physical BC. Don't know if Nintendo does either, considering how they've been pushing digital this past generation so hard.
