Wild guess here. Epic has been partnering with Disney a lot recently (star wars, McQueen, nightmare) so my thinking has brought me to a an epic disney rocket pass! The map will be disneyworld resort/park, the rocket pass will have tons of movie inspired items and crap like that. Not sure what car it would be, but honestly it doesn't matter cause we're boycotting.

Dylbobz has said that a leaker said the theme might be 'Retro', but im not sure
