How would the Gruffalo fit the lift simulators at the end though?
Given the cost of them, I would imagine any changes made to Charlie (whatever they are) would incorporate those lifts, unless they're truly buggered (which would be of no surprise)...
Thing is we don't even know if anything will happen to Charlie, and if it were being rebranded we'd know about it now rather than it kept as a secret, as we know Merlin are awful at those...
