To be honest, I can't see that happening. They will never create a setting which leans on the tropes of past fantasy.
Thing is, this is happening genre wide. This conversation that we're having now has been ongoing for a long, long time in genre circles. I remember listening to podcasts like Starship Sofa and Escape Pod talking about this sort of thing twenty years ago and I'm sure it's been going on longer than that.
Thing is, it's finally caught up to D&D. D&D, particularly in light of D&D becoming far more mainstream, finally has to deal with the incredibly racist underpinnings of Appendix N authors that we generally just accepted as "the way things are" for far too long.
Let's be honest here, most of the works on Appendix N are really, really offensive. They're misogynistic, racist and bigotted. That's what fantasy WAS for a very, very long time. Now, we have to try to untangle all that garbage from our hobby, bundle it up and shove it out the airlock so we can move forward with a game that isn't telling about 2/3rds of the planet that they are less valuable than a bunch of white dudes.
