I believe it could be real, but that seems like an insane price for Disney to pay for just for rights. Are they talking about getting full ownership of them (as opposed to just licensing)? Given the massive bucket of IP Disney already owns, it doesn't make much sense to me for them for them to spend anything in that range when they could use that money to just better develop properties they already have.
$2B could pay for a bunch of rides and TV/movies productions off of stuff they already own like Marvel, Star Wars, Pixar, etc.
