So Dragonflight is pretty much reality unless it's some false trail planted by Blizzard, right?
And don't fall into same trap again. Name is too generic to believe any leak. Some people still believe old "Shadowlands" leak with N'zoth and Xiros was real because "leaker" got name right.
But for sure it makes revamp less likely (or maybe it's soft revamp with updating world without changing story/zones), Dragon Isles must be continent for expac like this.
