It seems this ship has sailed… Sadly we may never see any other characters with ultimates besides shago.
There’s a lot of people asking for this feature at this forums. Up to now, this is all we have:
Ultimates are a “just for fun” feature. Not for tournament purposes i guess. If there was a variety of finishers surely we would see them at the tournaments more often. People dont do it because there’s only one finisher in the game. Stage ultra kinda accidentally happen sometimes.
I think you’re right. Ultimates would be another sweet ride for KI 2017.
