A bit early yes, but what are some possible expansions that could come after Shadowlands?
In my view, a definite one is going to be us having to fight Yrel's Lightbound. I really think that they are the new Burning Legion, and will be a major threat very shortly.
The other expansion I see on the horizon is an expansion dealing with the underground Goblin continent of Undermine. Undermine is a classic piece of Warcraft lore, and was even a planned continent in early iterations of WoW. There's even a nice open sport to the west of the Maelstrom where a few new continents can go, so I think Undermine will be located there. I also believe that Blizzard is going to tie New Gadgetzhan and the underground mechanical war to this expansion.
What do you think the next WoW expansions will be thematically speaking?
