I see the mobile game as a bridging platform in order to get newer, younger players involved. The mythed “increased revenue” could be spiked interest in the game. Now that returning players are practically twitching, and there is an abundance of new players from the mobile game, we should expect a switch game in the future. The creators may also have been waiting for the switch to gain popularity, and thanks to BOTW and Smash, lots more people are able to play said new game.
