I don't know. Honestly how many blockbuster franchises are born on unpopular console platforms to begin with? Pikmin on GameCube did well, but it wasn't some break out blockbuster.
Shenmue and Jet Set Radio tried very hard on the Dreamcast, but no dice.
Splatoon probably will sell about 1 million LTD if its lucky.
Even though I like that Nintendo is willing to take a risk and make it a new IP, I'm not entirely crazy with the art style being used (looks like a generic Cartoon Network animated series). It probably would sell 2x-3x more if it was called Mario Paintball.
