It's possible to hookup an external GPU via USB-C/Thunderbolt to a laptop. There's actually a lot of those out in the marketplace.
I don't see why that couldn't be done with the Switch. The only challenge would be in making in small enough and with enough cooling power - which would be rather easy if you simply have an extra 1-2 Tegra X1s in there.
It's a clear winning proposition. Nintendo gets more 3rd party support. Publishers get to put games on the best-selling platform. nVidia sells more GPUs.
The only drawback is possibly having some games that don't support portable mode - but that can easily be overcome somewhat with a PS Vita remote play like solution.
I predict NX launches in 2017 - not 2016
