I think they'll have a solid 2015 in part because some of these games have likely been in development for a very long time. Xenoblade is probably nearing 3 years in development by the end of this year.
Yoshi's Wooly World was first shown like 2 years ago and when it was shown it probably already had been in development for 4-6 months at least.
Splatoon was fully playable last June, I think another 9-12 months of development there should ensure it being done.
Fatal Frame V is finished. Mario Party is probably very close to being finished.
Mario Maker is a small project that can grow via DLC.
