Whatever they are working on, we don't want it and Miyamoto will make Nintendo believe we want it. 

Recent rumors (from Emily Rogers) say that Nintendo wants people who play the Splatoon port on NX to be able to play with people playing it on Wii U, nobody who knows that a new console is coming out would buy an old System just for one game, especially if it's rumored to get a port (hence it might be upscaled). It CAN be said about every Wii U game, but the problem is that Splatoon is up there in the top games for the system, stuff like The Wonderful 101 isn't.

I think they're mostly focused on getting their proverbial shit together in general.

Jokes aside; anything and everything NX related would be their primary focus now, that and mobile apps/games for actual profits on the platform.

I disagree. They're quiet because they're like the only game company that wants to surprise its consumers. Like Could in Smash, nobody could have called that and it got the response that it did because it was kept a secret from consumers. I like being surprised rather than spoonfed every detail.

Xeno X2 or GTFO.

QoL, which probably means more games like Nintendogs or virtual rock gardening (which actually sounds nice).

Backwards programming from Amiibo. Amiibo will be the starting point, then they'll say, "okay, we've thought up this awesome Amiibo grouping of characters, now think of a game to go with it."

Animal Crossing: Downtown Tokyo.

Project Robot Metroid. You play as a Federation Engineer while they builds giant robots to use to defend the planet against invading giant robots.

3 different platformers.

An EA exclusive release of NBA 2013.

Retro is allowed to have a new IP after they wait to ask Miyamoto while he's drunk at the hostess club. It turns out to be really good.

^Wow, very funny

Absolutely Nothing :P

they still have a lot of their audience, just only on handheld. The 3DS is older than everything else currently out yet is outselling the Xone and by far the #2 hardware sales system (when considering home and handheld).

Nintendo still clearly has a very large fanbase, it should be simple to get those loyal to the 3DS to try the next home console if they're just smart about it and do like a shared library 

That should not be hard if they just make proper WiiU emulator for NX. Like MS did with X360 games for XOne. Also there is still possibility that NX will have Power-PC CPU so it will have hardware backwards compatibility with WiiU
