If this comes to just 3DS then I will be mega-pissed off, but equally it makes total sense for it to be on both 3DS and Switch.
The problem is, from a short term business point of view, you can make more money off the 3DS userbase. However Nintendo need to regain the trust that they'll support their platforms properly. I know a number of WiiU owners that were happy they got some really good games, but still pretty pissed off at the weak support of the WiiU, and they're dubious about getting a Switch as a result. I'm guessing you all do too!
