I'm hoping that the cane means he won't be a direct copy-paste from Injustice 2, like how Sub-Zero/Raiden in Injustice 2 were pretty much copy-pastes from MKX. Yes, they had new properties on their attacks and SOME new moves to help them fit better into the new game, but they were mostly just a modified MKX versions of the characters.
Hoping he gets a new stance, new moves, and that the cane plays a big part of his kit similar to Bartitsu Bo' Rai Cho -- but with more tricks and gimmicks. What if he has a blade that can come out of the bottom of the cane? The head of the cane looks like a hammer, so maybe he can swing it Shao Kahn style? It's probably one of his gear options too, so I hope he has canes inspired by The Penguin and Riddler.
