Yeah, Yama tsukami needs to gom back, along with shen and lao-shan, imagine fighting shen in the new and improved battlequarters, and how fun it would be to fight lao with one of the switch weapons.

I reckon the only unconfirmed areas will be arenas unfortunately, just doesn't seem likely to have more (unless they pull a freedom unite and have ALL the previous areas available, because that will be awesome.)
