We are now used to it: the Fortnite update content is deployed on Wednesday and not on Tuesday. Epic Games has announced that the patch notes will be implemented at 4am and will require a downtime during which time the game will be inaccessible.
Season 10 is coming to an end, Season 11 is about to start and Epic is apparently planning something huge for the occasion. Numerous datamined game files suggest that the island as we know it will be disrupted.
We should also expect an imminent takeoff of the Dusty Depot rocket. The Scientist just finished it.
If most of the changes don't occur today, the clues we have give us a lot of information on future events in-game.
