The only way I can see the NX succeeding is this

The handheld would do OK but still likely suffer further erosion as it doesn't really address any of the core issues plaguing the 3DS (that is namely the loss of kids/casual players to smart phone/tablet gaming and the free game model they offer).

That console likely wouldn't do very well at all, probably 10 million or so LTD.

If the console is that underwhelming I don't see anyone but Nintendo fans buying it, and even then probably just the most hardcore part of their fan base.

Also the portable would be so close to the console in power, then why not just let the portable output to the TV? Most people would not want the console anyway.

I can see it happening. Considering a lot of people preffer Nintendo handhelds over home consoles, and the tech between NX home console and handheld is bound to be similar if not identical, I can see the home console NX being just a NX TV, a miniconsole with the handheld version as the controller. If it is cheap enough, it might find success as a complementary console and as a handheld. It would not use disks, it would have to be cartridge only.
