Five Nights at Freddy’s creator Scott Cawthon recently announced that he was pursuing a current-generation console release of the original games. Cawthon has been replying to fans in the series’ Steam community, and one reply to a fan was about bringing the franchise over to Wii U. Unfortunately, Cawthon said it was unlikely. He gave his reasoning, stating that he “doubts the Wii U will be thing by the time a console release is ready”.
As for the NX, it wasn’t mentioned. It’s not out of the question, though, as the console versions are not expected to release until “at least 2017”. The NX is slated for a March 2017 release, so the odds that the NX could see the Five Nights at Freddy’s franchise is much higher.
