help me made my mind up

i got myself a Dji Osmo 360 this summer, with the idea that will come out a dive housing, unfortuanlty i don't think will ever come out due the camera form factor, my mainly use will be for scuba diving, so i was wondering to get a traditional action cam as well, and then in case Dji will release a dive case for the 360 i will get that, now my question, since there are some offer on insta website would make sense to get an ace 2 pro now with the idea to integrate in the work flow in case Dji come out with a dive case or to wait and get a Dji osmo 5 or 6?
