My aunt is from that dimension too. She said there, The Order is probably their GOTY, although The Last Guardian is proving to be stiff competetion for it. UC 4 flopped and sold about 183 copies.

Better ask Soundwave, judging by his matter of fact posts on all things Nintendo related he is a regular traveller through that portal.

Now everything makes sense! :o

Meanwhile, at a future Nintendo financial meeting...

Investor A: "Mr. Iwata, your company is doing much better in video games sales at the trans-dimensional market than our dimensional market. Do you have any plans to shift more resources to that dimension?"  

 Investor B: "I just want to let everyone know that my trans-dimensional daughter enjoys her Wii U much more than my own daughter in Japan."

My aunt told me that the NX is actually a machine that transplants a chip into your brain while you sleep so Nintendo can monitor people's brainwaves. Zelda U is really a game that has over 4,000 subliminal Illumanti messages and the reason it was delayed is because they want it to be over 10k.

Ever since the Ark crashed here 65 million years ago, Soundwave has been incapable of interdimensional travel.

I've played Zelda U already in uberverse. In the ending Link befriends Ganon and finds a PS4 that lets him play The Last Guardian. 

True story. 

Metroid Prime Time

Zelda won't be trans but from what we've seen Link might be.

Everything makes sense now! The "X" means cross (dimensions). This dimension is finally getting NX, then we can finally have access to dimensions that already have this system. Nintendo once again is making the blue ocean strategy creating a gimmick that attract dimension's travelers enthusiastic .
I just hope that the games from other dimensions work with the system in this dimension
