@op, i fully expect a Paper Mario, because it seems to be just one of two games Intelligent systems knows how to make (sorry Advance Wars fans). Ballsy list, overall...maybe FZero makes sense given how long it has been.
I would argue that a “new-new” Super Mario Bros should be a priority for Nintendo. This means:
A soundtrack on par with Mario Galaxy and Odyssey
Refreshed play controls
Change up the level design (toss the three coins, update the goal post)
New enemies and power ups, lots of them
Playable Peach, Daisy, Wario, Waluigi
Maybe more ambitious use of the map screen
Maybe a new villain
Super Mario Bros can sell 25 million again, but it means putting in a serious effort.
