There are rumours that Lego will release a rollercoaster in August this year. The Lego community believes it will be motorised. You might need to buy the electric motors as an added feature. The motor will of course be nicely integrated. The Lego community believes the roller coster carriages will have similarities to the Lego Joker Manor set 70922. The set includes 11 mini figures, candy stand, ticket booth and other fun features. Watch out!
