Nintendo fans make such a huge fuss about this game coming to Nintendo platforms, and once it's announced as a stretch goal, 24 hours pass and a mere $100,000 in funding has been raised. Let's be realistic as well, out of that $100,000 raised, most of it probably wasn't from Nintendo fans considering that's about how much it's been increasing on a daily basis other than the initial funding that was over $1m in a single day.
Once the Wii U is announced, instead of funding the project that they were making such a big deal about, they're now bashing the project because "it should have been on the Wii U in the first place," or any number of other arguments.
I personally think the Wii U has the best software currently than the PS4 and Xbox One because it's not literred with ports and actually more than a couple quality exclusives, but it's all Nintendo funded exclusives. And maybe the constant comments are right about this is why third parties don't support Nintendo consoles. Nintendo fans don't even purchase the games they make such a big deal about, so why is some developer going to randomly toss a game on the system with no knowledge of whether Nintendo fans will support it or not.
