Pokken and Fire Emblem are farmed out projects, another tell tale sign when a Nintendo console is nearing the end is 50% or more of their announced games become farmed out projects and support from the main Nintendo teams slows down (see also: the GameCube's final year).
I agree with a previous poster that said NX centrally is basically a portable that can run Wii U graphics. Maybe there will be a home console/dock companion to that which can do better graphics for television play, but the portable will be the main driver of the product line.
As such, the transition to NX will likely be pretty seamless and several games could be "cross-gen" (like Zelda and Pikmin 4) depending on what Nintendo views as a priority.
