I for once expect more nutpunch variations for Johnny Cage.
For example, a run-cancellable nutpunch that would leave him safe on block and plus enough to continue the combo on hit, while adding a ton of gravity on the non-MB version, so that any follow-up juggle will drop, forcing him to continue with a standing combo ala NutRC-->113xxNutRC-->113xxNut.
Or a nutpunch that can be special cancelled into another nutpunch: on hit, the second nutpunch can be blocked, and on block, there will be a gap for armor/backdash; the nutpunch itself would be around -9, but the delay between the chained nutpunches would still make it possible to stagger. Then, Jhonny would also be able to mix the opponent with MB nutpunch (not to be confused with EX nut), so that if they backdash and then move in to punish, they'd get hit back.
Honestly, no new ideas for mimic nutpunch, other than just making it a slightly different version of mimic upperrcut: combo on hit, safe on block, mid, combo extension, big plus frames on block.
Oh, and NRS *must* add instant-air nutpunch. It think it would solve all the problems Jhonny currently has, especially his crap anti-airs.
