Now the rumors can finally stop: NX is a home console, and not a "fusion/combination" device

I agree this is the likely inference. But it's hardly a logical deduction. The NX version could be the same as the 3DS one. I think the fact that we have almost nothing announced for the Wii U next year and still quite a lot expected for the 3DS does make your assumption likely correct though.
