i don't think that things will go back the way with DOA3-4 , any new doa game will be heavily micro transaction, only now TN researching new way to do it. (gacha)
both two different team
remastering past DOA games like 3 or 4 seem unwise cause TN don't want to DOA3 or 4 to compete with DOA6. not profitable
so in the end we have to wait for some sort DOA game by this guy named nakamura. KT AND TN seem to favor him.
