To be honest I don't see Nintendo's dev teams being in any rush to make a massive leap in graphics tech anyway.
The Wii U only launched 4 years ago and they're only now really getting the hang of HD development. To have another full generation leap so quickly I don't think was ever going to sit well with Nintendo.
Sony/MS used the 360/PS3 for like 8 years, and even they both had big headaches and delays of software transitioning to the PS4/XB1. First year for both of those systems was very mediocre software wise.
NX being somewhere in between a PS3 and PS4, maybe even hedging closer to the PS3/Wii U range wouldn't surprise me. Kinda sucks if you're a graphics enthusiast, but if its portable then at least there's some utility that comes out of it.
Right now I'd be pretty estatic with a NX that is about a little less than a XB1 in "home mode" (provided it even has seperate power modes). Nintendo games would look phenomonal even at that level.
