Of course it is to be expected. That is why I hope Disney is smart about the opening and has a plan to manage FP+.
Yes those educated rumors were started with facts direct from Disney with ticket and CM block out dates etc. Too many other things are often put out there that people make up, copy for other sites etc. And for things like ROL when you keep throwing out guesses, yeah you will eventually be right, but doesn't mean you were right, just played the odds that eventually it would hit. We are too far out to start planning around SWL rumors other than what Disney has put out there.
