I really want it to be Roger Jr fighting this time not his mother doing the fighting for him if he appears.
But considering they haven't done a proper timeskip yet he's most likely still in the pouch.
Yeah, I'd like to see that happen eventually.
Honestly, I think it was a mistake having so little time pass between Tekken 4 and Tekken 7 (it's like a year, if that). Seems incongruent with the events that have transpired in that time (3 or 4 iterations of the same tournament, and World War III).
