Epic Games rarely surprises players with content because all of it leaks ahead of time as said content is worked on, courtesy of the game's files.
Picking through the files of the game's recent update, dataminer FNBRUnreleased noticed that both Ballers and Hoverboards, two vehicles not currently in the game, have been updated, which suggests work is being done to them, and of course this, in turn, suggests they are returning sometime in the near future.In addition to Ballers and Hoverboards, Epic Games also updated the files of Golf Carts, another fan-favorite vehicle we haven't seen in a while!
