That's kind of the life cycle of scoops in any form of news tbh. Multiple people can hear rumblings over a course of time, but not be confident enough to report on them yet and wait to gather more information for a full report before making it public (or like
@Alicia expressed yesterday, may fear leaking it too early could affect the deal itself). Not to mention some people hear things, but may not be able to yet discuss them for the sake of the source(s). Once the first person decides to bring the story to light, it's out there. It's easier to go "yeah, I've had rumblings about this on my side as well".
A perfect example of this in the non-theme park world is this gem:
Reporters work on scoops for a
long time sometimes before hitting "publish" on something. But once it's out there, it's out there.
