If the rumors are true. It being set in wakanda with black panther. With the main star no longer with us. They have to go back to the drawing board since he can not film or record any new dialogue for the ride. They'll either not use him. Cgi him/get a voice actor/piece together previous dialogue to make it fit or go into a whole new direction.
FYI Black Panther is a mantle which will be passed on.
