"If" we do get it, it'll be interesting to have both Potter lands in one park as opposed to two in Florida. Kinda cool!
If they do utilize Hogwarts Express, I wonder how they'll handle the elevation/steepness of going from the upper lot to the lower lot.
You know when would be cool to potentially announce Diagon Alley? During the grand opening ceremony of Hogsmeade next year, similar to Apple's "oh...and one more thing."
