Preach.
I find my predictions for NX exactly in-line with yours AniHawk. I don't think NX is a console at all, but a platform similar to Netflix. The platform will probably launch in 2016. The platform may or may not even be available on the 3DS and WiiU in some fashion.
I strongly feel Nintendo's new strategy for game distribution might be entirely digital, with retail items (such as amiibo's or 'download cards') being used to represent games if consumers desire. I don't know if their next consoles will include disc drives.
I can see Zelda and Retro's new Metroid project launching on NX and WiiU at the same time, but by that I mean you can buy the retail WiiU packaged disc, or you can download it for their NX service full-well knowing you'll have it immediately on future hardware. Imagine buying Zelda for WiiU digitally, knowing when their new handheld comes out in late 2016 it'll play the game immediately.
I also strongly feel their next consoles won't have a lot of *new* games at launch. As you said, they need new hardware for 2016 if they are going to return to serious profits. However, so many of their 3DS, WiiU, and virtual console games will have moved to the NX platform, by the time their new NX-supporting console/handheld launch, it'll have a massive library.
The last thing I feel like they should do, but might not, is offer some sort of Netflix-style service for NX. Pay 6.99 a month and have every NES-N64 virtual console game on the platform, with new additions every little while.
Nintendo's retail representation will still exist, but not in the slogging packaged game market, but in amiibo toys, controllers, hardware, and download cards.
This is my prediction, but I feel like it's an innovate and logical way to move forward. It simplifies development, it aligns their platforms, and it offers an innovative and forward-thinking way to play their games.
