your reaction smash NX is announced at e3 touts "all characters and stages from wiiu and 3ds plus all dlc" and then it says " Featuring returning fighters" and it shows ivysaur, squirtle, pichu, young link, ice climbers, and snake
(lets assume for now that wolf is dlc for smash 4 if not add him in plus 1 newcomer ((money being on inklings if they dont get in via the ballot) then it says "and new stages" to which we see poke floats shadow moses, great bay, summit, and a stage based off of gyromite (and venom if wolf is in this reveal plus a stage for the acompanying newcomer)
insane what if scenario but man can you imagine a smash game with every single character
