Ghostbusters makes a far amount of sense--I can only think of four IPs its arguable "no one wants"--GB, BJ, Chucky and ST. I think a lot of guests would still be excited for ST, even with the first house flopping I think a BJ sequel featuring an ersatz Jenna Ortega would still get buzz.
GB: FE looks like it might fill the "PG" slot that FNaF would (both the kind of thing to have toys in the Target toy section rather than collectables). Plus Chucky was universally (no pun intended) trashed last year. This makes a certain amount of sense, specially with the park going all in on the franchise apparently.
