I am looking forward to SMB Wonder, but I am just as much looking forward to Nintendo announcing its sales milestones. Apparently a lot of people need to be reminded how big of a deal a REAL Mario game is.
It doesn't matter when Switch 2 launches, whether or not it's backwards compatible, whether or not a Switch 2 version is a day 1 launch title or is coming later down the road. This is all so far in the future that the proposed contest of this thread is a done deal by then anyway, nevermind that regardless of Switch 2, SMB Wonder's Switch version will keep on selling lots.
Legend11 correctly predicted that GTA IV will outsell Super Smash Bros. Brawl. I was wrong.
