I've been waiting for them to just 86 GMR for over a decade. If they're not going to give it a proper update, please just rip it out and replace it with something better. At this point, the ride is hardly better than the worst ride on earth, that being Hollywood Tour at Phantasialand (which is in fact a rip off of GMR, hah). Well it's actually a rip off of pretty much anything Disney or Universal was building in Orlando in the late 80's mixed with Pirates of the Caribbean for some crazy reason.
By the way, Phantasialand is quickly advancing to become one of the top non-Disney parks on earth- people should take note. I already prefer the place to all Amercan theme parks aside from Disneyland, Magic Kingdom, Animal Kingdom and EPCOT. It's about on par with Islands of Adventure. Klugheim is every bit as impressive as Potter except for the strong IP/tugging at heartstrings that Universal's achieved with Potter. Taron and Black Mamba are better than any coasters at Universal too.
