I'd say get the Wii U. There's really no telling when the NX will come out, meaning you could be waiting, not being able to play the games you like, for possibly over a year if the NX gets delayed. Plus, the good thing about the Wii U nearing the end of it's life is that in some places it's cheaper. If you buy a Wii U you'll be able to buy and play plenty of games, and when the NX comes out, when you get it you won't have to waste a lot of money buying heaps of games all at once, as you'll already have a bit of a stockpile from the games you bought when you just had a Wii U. Also, a lot of games for the Wii U that depend on online multiplayer, such as Splatoon and Mario Maker, may have become much less popular and by the time the NX comes out they might even be dead games. I think you should enjoy the Wii U while it lasts, and feel no possible regret later on. Hope this was helpful!
