It is fully possible that Blizzard has a "B" team working on the side to remake assets and rebuild Kalimdor and the Eastern Kingdoms, while the "A" team builds new expansions.
A world revamp could launch with 10.3, 11.0, 11.3, 12.0, or anywhere in-between those patches, as a free update to all players. While the underlying cause of the revamp might have something to do with the expansion's theme (for example, Azeroth being corrupted or purged from her corruption), the story of the expansion itself doesn't have to revolve around the revamp.
We could be going to a new "continent", and also get a revamp.
That continent could be Avaloren, a vast landmass on the other side of the world.
It could be a collection of tropical islands somewhere far out at sea.
Or it may be a huge system of underground caverns, including underwater zones, in a new domain for Queen Azshara.
