Aw, that's lame. I wasn't super excited about RMC trains in general, but I thought it could be a sign of things to come.
And just to start another rumor, SFDK is officially dropping the Harley Quinn Crazy Coaster. Popular assumption is that it will be scrapped, but I could see them sending it back to Skyline to be retooled somehow and recycling it. Skyline still advertises the model on their website, so unless they are abandoning the model, they should still be on the hook for providing SF with a useable ride. Since this was essentially the prototype, I could see them giving it an overhaul and a relocation as a "new" ride.
