Diamondback has been seen with cranes around it, with the speculation that it is being torn down which isn't the case. Instead, we could be in for a treat and get an even faster lift hill like Orion or have the slower lift hill. Personally, to me I like Diamondback's slower lift hill to create suspense since it is revolved around a snake, whilst Orion is revolved around Orion's belt and space, launching you fast up to make it feel like you're being launched. Who knows though! It'll be an exciting surprise they haven't announced yet.
