In all honesty it depends on what PS4 fans think. They decide the status quo as their console has the numbers as well as the fanbase.
They can decide that NX is
A. Part of this gen and replaces the WiiU, thus NX launches at the distinct disadvantage of being 3 years behind XBox One/PS4's 2013 release. If they spam the internet with this opinion, NX will be known as the console that "launched in last place" and will be another WiiU sales wise. Nintendo basically goes from a 13 million install base to 0 where as Xbox One and PS4 continue as usual.
B. NX is next gen. This means that this is PS5 competition, and Sony will have some ground to cover when it eventually launches.
I don't think PS fans will take kindly to this one, as A. seems more easy to accomplish.
Xbox: Best hardware, Game Pass best value, best BC, more 1st party genres and multiplayer titles.
