What will sell better, Splatoon 2 or Mario Odyssey?

[SamLeheny]

Ima say Mario, just because for a primarily multiplayer game, it seems a bit soon to be releasing a Splatoon sequel.
They may be flawed expectations, but when I hear that a single player game I liked it getting a sequel I think "Sweet! More of this please!"
But when I hear a multiplayer game I liked is getting a sequel so soon after the first, I think "Oh, gonna make me pay for it twice eh?"
