There were reports that The Rock did not get along with his co-stars in the F8 of the Furious, but if they could find a way to reconcile maybe they could have Hobbs chasing down bad guys in a Pikachu costume.
Money mends fences and the money that the last fast and furious movie made caused the Rock to rethink how long he was going to be mad at Vin Diesel. Looks like they're ready to put aside the beef and go out there and get that money.
