Not worried about the launch window. Moving Zelda to the NX launch window buys them all the time in the world, and EAD Tokyo is due for another Mario platformer for late 2016/early 2017 too ... so that 1-2 punch basically would be enough with the usual other types of games (like 3rd party ports) to ensure a very strong launch.
I think they purposely also denied the Wii U a "real" Animal Crossing game, and that game is deep into development for NX as a result and will be able to release early in its life cycle (within the first 8-9 months).
