For the record, Pandora was 5.5 years (Sept 2011 to May 2017), not 7.
So indeed, the analogy is perfectly reasonable for Osaka and actually a bad analogy for Orlando because that project was pushed back by 18 months to 2 years for completely different reasons.
5 years is a completely appropriate development cycle time when you announce something at the inception of a licensing partnership. People seem to forget Tom Staggs in September of 2011 literally said: "From start to finish, a project of this size and scope takes about 5 years to design and build. We can’t give you an exact date but we know that when it’s complete, it’s going to be a truly unforgettable experience."
So really this isn't all that surprising.
