The bit that's still confusing me, is the launch, I've been told of the new enhancements to it, but apart from a few new motors and a clean to the actual propulsion system, don't expect a totally new technology. Unless its SUPER secret at the moment.
*Edit* Thinking about it, How much power would an electromagnet launch save universal, think of the marketing The "GREEN" coaster... (at least greener than before)
