The latest Sundering Adventures like Murder in Baldur's Gate got DnD Next (Playtest) Stats. Has WOTC mentioned anything about updating them to the final 5E Version?
I'm not so sure about that, the Monster Stats have changed dramatically over time. On the other hand 5E doesn't care to much about the balance between Monsters and Players so it might be all right even with big Stat-Changes (Princes of the Apocalypse includes Random Encounters with over 10 times the Deadly Budget ).
