DOA was great during the OG Xbox, early 360 era, but a lot DOA's long-running issues are quite frankly because of Itagaki. The focus on sexuality in an FG, the creation of DOAX:BV, and his anti-competitive game design (most apparent in DOA4 compared to DOA5/DOA6) are a big reason why DOA struggles in the FGC and to a lesser extent; the mainstream.

Maybe we could've gotten a new DOA game if 6 was a proper follow up to DOA5LR (which it wasn't), DOA6 devs didn't including outfits like Microkinis (like DOA5 which were behind Master Difficulty) or Outfits that showed tons of skin like Rachel's Fiend Costume (which got covered) or Phase 4's Arnice Demon Transformation (which got removed). DOAXVV in terms of Outfits & Fan Service Feature is what DOA6 should've been.

DOA Dating Sim was thanks to DOAXVV Popularity especially with the new girls they've introduced, plus DOAXVV has content like Sex Appeal which makes Microtransactions valuable which is something Publishers would care about having. DOA Stage Hazards wouldn't be anything they can monetize or not without backlash if KT attempt to charge money every Level Hazard or Multi-Tier Level.
We need a producer with a 10th of Itagaki's amount of talent.
