What I want them to do with the next game they won't do. Which is take the moves and gameplay ideas for Luigi from Smash Bros over the years...and give it to Luigi. I want to see some Luigi Missile, Flaming uppercut and tornadoes in a 2D platformer. And a game with the game engine of New Super Mario Bros would be perfect for it.
Thinking more logically however.....what everyone has been asking for is probably the best idea. Where New Super Mario Bros was harking back to Mario 1, the next game should pay homage to Mario 3 with similar power ups, environments and gameplay.
And if that's the case, all I ask is they do what they should have in Mario 3. Add additional levels with Koribo's Shoe (or make it a holding power).
Six upcoming games you should look into:
