I wish they'd go with "Underdark drow" and "surface drow" or something along the lines. A drow living in a drow society doesn't need to be actually "sworn" heart and mind to Lolth (just keep appearances, and not always that). I'd like to play an evil Underdark drow, but not necessarily one serving the spider whore. :P Other Dark Seldarine would be great, like Vhaeraun, Kiaransalee, Zinzerena or Ghaunadaur. Or a drow that's a hermit or a "ranger" living in the Underdark, but outside drow cities. Neither "Lolth-sworn" nor "Seldarine".
Similarly, "Seldarine drow" suggests drow that specifically worship Seldarine, which is very specific (especially with the lore blurb, very specific). What about surface drow that worship other gods, or no particular god? Eilistraee seems perfect for this "Lolth-rejecting good drow" archetype, but she's not a Seldarine.
This would be a much better idea. Dialogue options would be mostly similar to what they have I think, maybe only a couple would need changing.
What annoys me greatly is that they already have Eilistraae but not Vhaeraun. Really hoping they add in a lot more deities.
