It could be, however the "reveal" next year could be just a brief reveal, rather than details, release date, etc. If "NX" is indeed anything like the "Nintendo Fusion" idea I would guess 2017 release, or perhaps the release of the handheld equivalent only in 2016.
I think some people are reading too much into them "announcing" a new console, with regards to how it affects the state of the Wii U. It was a response to the announcement of putting games on mobile, to reassure that they plan to remain in the console business. If Sony or Microsoft took a big step that made people think they were moving into streaming games or PC only in the near future, they would likely state that they "are still working on the next Playstation / Xbox", but it that wouldn't be cause for "Sony giving up on PS4, already planning PS5!!"
