Recent retail codes and the announcement of the new Knight Rider film suggest that this may be another brand coming to Lego Dimensions next year.
This would certainly follow up on existing retro franchises in the game already like Back to the Future and Scooby Doo. Other possible franchises include Fantastic Beasts and Where to Find Them, following up on the previous Harry Potter video-game.
Oh my! Thsi would be so awesome if it happened! would love to see The Goonies as well!
