User blog comment:Plasmaster/Patch 1.1.6?!?!/@comment-25275196-20160521103256/@comment-27665259-20160521130920

There might be more patches (i wont be surprised if there was more) but i don't think there will be any more DLC (even if Sakarai said that, he is a troll so there could be a slim chance 1 more DLC character was in Sm4sh.).
