It's obviously more likely that Octopath Traveller ends up in a Sony/Microsoft console than MARIO+Rabbids. That's not even up to discussion.
Perhaps. But first and third party are not defined by what a person imagines might hypothetically occur at some undetermined point in the future. And console exclusivity does not define first/third party either - which was the point of my comment.
M+R is, by definition, a third party game.
