I'm hoping that smash-icon token in the trailer is was I thought it was (there was one, right? I think Mario got it and it cut to a scene where he had devestating power). I'm hoping they appear occasionally and when your character gets it, they're granted devestating power. Please, anything... I'm sick of the Pokeball (sorry, don't know the code for the e with the accent mark) being the item all the CPUs are drawn to. They don't even go after Bob-Ombs. Speaking of, how about more Bob-Ombs? Having bigger Bob-Ombs the size and weight of crates would be pretty nice to throw at your annoying enemy.
Also, I want NO LIMIT to the size you can reach by getting more and more Mushrooms. When you're big and get one, GET BIGGER. Get another, grow again. Another, grow. Keep going until your shoe is the only thing visible onscreen. Same for Poison Shrooms. Keep shrinking until you're not even a pixel high. Change the shrinking sound to the classic sound, too.
