I kind of assumed it was a 3DS game by the name of the thread and the graphics in the video. Which would've been pretty sweet if that were the case.
I'd honestly prefer if all Nintendo games from this point would be for the Switch since it's a handheld too and so I won't have to carry around two devices for the same purpose.
Well at least there is a Vita version of this. I'll probably pick that one if I decide to get it. For a PS4 game it really looks too meh. On a huge flat TV I don't want to see such blocky graphics anymore to be honest.
