Dnd 5e is written with a turn based system in mind. ALOT of things dont work if you suddenly make it RTWP. Heck, alot of feats work with reactions that just completly fall out of the window if you make it real time.
BG1 and bg2 did it very nicely but it was still a big departure from the rules set. Which were written with turn based rules. And considering theyre trying to stay close to the pnp rules set I dont see them making it real time.
