Honestly? It doesn't look like he will in my opinion. I may not know much about Tekken, so my perspective here shouldn't be taken too seriously, but he seemed a little tricky. Especially considering that Sakurai literally had to comment "Is this Smash or Tekken?" And of course let's not forget that Heihachi only wasn't in Smash 4 because Sakurai thought translating Tekken's mechanics would be difficult...
