I answered "Keep FR" not because I want them to keep it, so much as I think they will keep it in 1DD, since I feel it's equivalent to 5.5e rather then 6e. However, the question was vague as to whether or not the OP meant 1DD or a future edition.
Although I wouldn't mind seeing Exandria (or one of its continents) become the default setting in the future. In my campaign, I've switched from FR to Wildemount because I find FR to be too massive and overwhelming. Wildemount has a smaller and cozier ambiance that I prefer. Plus, after watching Critical Role's 2nd campaign, I feel I'm more familiarized with the continent than I could ever be with FR, despite reading all the Drizzt books.
