I'd be...okay with Mummy getting replaced. Not happy, but not majorly upset either. Put it this way: the last time I rode it, I did so with a straight face and my fist on my cheek. I think it's time, y'all.
Now, let me pose this thought: would the Mummy space be good real estate for a WWE ride? Not that I'm gonna pitch to Mark Woodbury or anything, but I've been dreaming up ideas and that building would really be the only place where something along the lines of what I'm thinking (like Spider-Man, but a lot more elaborate, plus a Fallon-style Virtual Line lounge) would fit.
