Can't say, KT is going to appear at NGPX on the 23rd of June there might be an announcement for something DOA related (HARD maybe). Then again, Atlus will also be at the event so its safe to say that we're getting Persona 5 Scramble news. If we won't be getting there, then maybe at the next PS5 presentation, if not, then most likely after the PS5's release......or not at all.
If there was a DOA game on PS5 its not going to be at launch, and would be mention after PS5 release. Team Ninja still has that new IP game that is coming for that console. Me personally would prefer if there was no PS5 release of a DOA game, just Switch & PC (DMM Games/Steam).
DOA6 will flop on PS5, I doubt it’ll come anyway since I don’t think KT would put any more budget into a DOA fighter. Clearly KT cares more about DOAXVV than about DOA as a fighting series.
