At any rate this is a welcome idea, as it'll give MK something more targeted to older kids, teens and adults. Very curious to find out what the two major attractions will be, and if there is a third smaller attraction in there. A more thrills-focused Ursula spinner or even a campy yet macabre show like the old Beetlejuice concept could be good complimentary additions.
If it's a Maleficent themed coaster I hope it's not a clone of Raging Spirits... since it's not a concept that will appeal to young kids, it ought to be Disney's most intense coaster yet while also having a similar level of detail as Hagrid's. Make it clearly a step above Big Thunder, SDMT, Space and TRON in intensity/scare factor. Everything else in MK is family friendly or fun/light thrills. Let this be very clearly meant for an older crowd.
For the second one, a dark ride around Bald Mountain using the Shanghai Pirates tech would be a cool idea for incorporating multiple villains, while having a spooky ride without a height requirement.
