Uh-hu.
There is no fundamental difference between Baldurs Gate and Neverwinter Nights.
Literally the exact same setting, they are both Forgotten Realms. They are even geographically close, too. Neverwinter Nights is located a bit further north, and even further north would be Icewind Dale.
So demanding a BG4, NWN3 or IWD3 - thats always pretty much the same thing. The only difference is Baldurs Gate is the biggest name among those three.
And they said they are not interested in D&D, not in a BG3 addon and not in BG4, they want to do something else.
So: long story short: Dont hold your breath.
It may very well take a decade or two before they return to anything D&D. Or maybe they will never ever return.
