you do realise PoE2 *had* to implement the choice because people were moaning so much about it not being a turn based game?
I don't think that's quite correct. If I remember correctly one of the team members believe he could translate PoE2 combat into turn-based system and after showing his concept he got greenlight and small resources to do it.
Nothing is impossibly I suppose, but considering that Larian so far has been rather critical of RTwP system (rather then PoE devs who openly expressed preference toward Turn based system) I doubt there will be someone with enough passion for RTwP to try to impliment it. But of course we don't know every one the team, nor conversations and thoughts they are having
