While I'm sad to see X go this does look like it could be a very high quality and good new ride, and will have tidied up a lot of the areas of X that needed work. If the concept art is anything to judge by then I'd say the corridors will all have been made to look like prison corridors or a hospital perhaps. It also appears that when you're on the ride itself the brake runs will be themed with different areas, I'd imagine with actors trying to grab you, projections, maybe animatronics. I'm curious to see if there's a soundtrack in the pyramid and what will happen between the break runs, guessing maybe intense music and some lighting.
I'm going to keep my hopes up for this until I see it in person, although I do hold everyone else's skepticism regarding actors staying with Merlin's track record.
