Taken from front page interview:
So will next expansion be a time skip? If so how far into future we will end in? Are they gonna revamp whole azeroth again?Time is different in Shadowlands. It is a construct or order and structure, which isn't a focus in the Shadowlands.
We will have to see how this difference in time will effect our characters when we come out the other end.
Not gonna lie, i wouldn't mind neo-orgrimmar.
