I'm happy they went with turn-based, personally. I don't hate RTwP - I have very fond memories of the original games and I also loved the Pillars of Eternity games(especially Deadfire). I feel for the RTwP fans, but I personally wanted a D&D 5e game more than a hard sequel to Baldur's Gate.
They could have avoid all this disappointment by calling it something else(and setting it somewhere else in the Realms!), but I imagine Wizards made the decision for marketing reasons.
