The only reason SE was cut was because it took forever to program in Brawl, and I'm sure they had their hands full in successfully developing both games. Regardless, yeah SE was awesome, and maybe we'll get a Melee-style Adventure Mode for DLC? At least for the Wii U since Smash Run is essentially that.
