Ok, so hear me out for a moment. Something just occurred to me.
We’re at a really strange point for Namco content. For Wii U, we had Heihachi and Lloyd costumes as DLC. We’ve seen neither costume yet, with one Fighter Pass spot remaining.
It can be assumed that getting revealed as a DLC Mii Costume counts as a disconfirmation. If the original project plan was to bring back content in waves, then depending on Pack 5 there could be a few implications:
1) Neither character is playable, and they both come back as Mii costumes with Terry or Pick 5. This appearance as a Mii Fighter disconfirms Lloyd Irving and Heihachi, as they were both costumes.
2) Neither character is playable, and they do not return as costumes. This would be rather interesting, given the size of both series (Tekken and Tales of). I must admit, I would be surprised most by this. It would imply they not only weren’t planned as DLC, but not even planned to return as Mii Costumes. Given who they are, that seems...odd.
3) One of Heihachi or Lloyd are playable, and the non-playable character would return as a Mii costume. This...actually seems like a plausible outcome.
Just thinking about it, it would be odd to not bring back both costumes, yet bringing them both back disconfirms them. However, there’s one “planned” DLC spot for the Fighter Pass, which was the original. The post-FP DLC is a different animal, but it only means something if Lloyd or Heihachi weren’t planned as costumes or playable...which would be weird to not plan them to return in any fashion from the beginning.
I hope I’m making sense here, but I could be wrong.
Tl;dr: I think it’s plausible Lloyd or Heihachi get directly confirmed as something in the Terry presentation or one of them is the final character. Both were Mii Fighter costumes in Wii U and are from popular series, therefore it would be quite odd for neither of them to appear in the base game and Costume waves as initially planned for Ultimate. This doesn’t mean they can’t come back later, but I feel it would just be...weird.
We’ll find out soon enough I guess...thoughts?
