Let's be honest though, we were all expecting this, and it's for a good reason as well, because the 3DS is about 7 years old right now. However, the thing about third games being developed for an older console when a newer one is out is not new - Pokemon BW2 literally saw the same thing with people complaining about it still being on DS when it was meant to be on 3DS, much like how people are complaining about why USUM are still on 3DS, yet Pokemon Stars was a trademark that fuelled rumours for the third game being on the Switch. The only difference BW2 had was a tie-in app for 3DS, Pokemon Dream Radar, but that was just a marketing ploy to tide people over to the 3DS ready for XY when it would release. If USUM do come with a Switch app then it could hopefully drum up excitement for the Switch game in this same vein.
