Well here's what I think...

- They saw how much effort got into put Xenoblade and wanted to top it
- They felt releasing it during the 30th Anniversary of Zelda made sense since this game is going back to what people really loved about Zelda
- The NX is releasing next year so they wanted to replicate Twilight Princess success and release it on both Wii U and NX.

 

Bingo. I think your Xenoblade portion hit the nail on the head.
