I feel your pain OP.
I would feel cheated in your situation; however, I've never personally purchased a Nintendo system and if rumors are true of the playstation 4.5, I would probably jump into the Nintendo wagon because of Sony's stupid decision making.
Let me explain why I feel it's a similar tale, but at the same time, very different orgins:
The WiiU has been selling misserably, and it hard for a company to change the image of a product once it has taken foot. Nintendo money would be better spent shaping the image of a new product, then to play damage control on one that is not selling and will cost a lot of money to change people's perception of it (talking about the wiiU)
Sony on the other hand is leading the competition; their current console is very profitable, but rumors have been flying that their is a new sku with vital hardware revisions that will make it more powerful than it's preticessor. They do not need to do this. They already have a winning product in their hands, all they need to do is provide a better PSN Service, Great customer care, Diverse memorable gaming experiences, and listen to the demands of PSN community. I would even argue that they don't even need to push PSVR.
I know Nintendo has done a similar move like the NX in the past with the DS, but to a playstation loyal who is not happy with what Sony may be doing, the NX seems like the logical choice. It would open up a new Japanese catalog of games and have similar specs with the Neo (PS4.5). To me it would be the most bang for the money if I were to purchase another console. In fact, I purchased three PS3's back in the previous generation (two for my house, one for my cousin).
I understand your fustration, but I see the NX becoming very popular with people like me if Sony pulls a Neo on us.
