That whole double-extra-secret drow idea seems like something that, if they'd waited six months on, they could skipped.The Good Ice Drow who are better than everyone else combined actually have gunpowder and AK-47s. Just watch.
Just do what's being done with orcs and goblins and such and differentiate culture from ancestries. We don't need two new flavors of drow; we just needed to see cities that weren't Bondagezerran.
As it is, it seems like we're going to get more "but your drow character is actually a good one" stuff in the 2024 PHB, instead of just the easier "drow are people: some are good, some are bad; don't make it weird, man."
I suspect the long lead time on writing novels, and WotC's desire to not contradict Drizzt lore, will keep things the same old, same old there.
