It's splitting the Nintendo userbase!
Just imagine this. You just bought your Wii U, you're enjoying all the nice games and you're perfectly happy with it. Then suddenly Nintendo announces a new console. A new console that not only does play Wii U games at a better performance and visuals but even has a bunch of exclusive new games and features. They're probably even stopping releasing games on the "old" console because of this.
I mean what was Nintendo thinking? They're splitting their userbase, basically making Wii U owners second class citizens. There are now over 10 million customers who are angry at Nintendo because of this yet they continue to go forward with this. They're gonna ruin all the good reputation they've build with the Wii U.
Consoles are built to last and not to be replaced with a new model after a few years. Have they even thought about how much of a strain that will be to their developers? They will now have to develop games for 2 different platforms and for most that's an impossible task, so they'll be forced to only develop for the new console which will leave all Wii U owners in the dust.
So I beg you Nintendo, just end all the rumors and the NX nonsense and stick to Wii U, like your fanbase does.
If you demand respect or gratitude for your volunteer work, you're doing volunteering wrong.
