its hard to confirm this since the last smash was released on 2 platforms. |
Even then, it sold really well on a platform that most people usually don't play competitively on (3DS) and on another platform that had very little momentum left by the time Smash came around (Wii U).
And about your comment of Smash Switch using Wii U assets, I wouldn't be surprised but I don't think it would matter. Every Smash game since the original has used assets from previous games. Heck, Smash 4 was basically built based off the Brawl engine and was modernized to provide a less rugged and more lighter feel than Brawl did.
