There will be more, the titans of Nintendo are Mario Bros franchise, Pokemon franchise, and the Zelda frnchise. Theres bound to be numersous characters from each of these, as there were from Melee (Mario had 5, Pokemon had 4, Zelda had 4). Thats 13 of the 26 total, kind of ironic no? I don't think so, they are what makes Nintendo big. With the raise cap of characters for Kirby franchise, Donkey Kong franchise, and possibly the Earthbound, why shouldn't there be one as well for the pokemon? They will probably be capped at 5 since its a nice number to work with, unless you hate odd numbers.
Pokemon Trainer is only one dude in one pokemon, so its fair game who the others will be. Deoxys is a AT, and with the new era of pokemon, i have my doubts for the more commonly known ones that were legendary (Mewtwo, so long once again), so if any other offer to a pokemon, i'd actually love to see 2nd and 3rd Generation pokemon (which also means one exeption of Gengar, my #94 1st Generation
). Its odd how the 2nd got the shaft as it did, but just one rep. Scozor was a favorite pokemon for a while, but maybe Ledyba to go on with some Cuteness to the franchise lol.
