I don't know that it's really that simple, though. Even if it's due to permitting issues with Anaheim they may not want to put that out there publicly to further stoke the fears of a cancellation. Then there's the risk of antagonizing the city departments (or city council) that they are trying to work things out with if the impression is given that they are trying to influence negotiations by going public. It's also possible that they are bound to silence by an NDA or something similar with whomever/whatever they are trying to work through. They know that they are losing runners every day that the delay goes on. Even as tone deaf as they can be, I find it very hard to believe that they are intentionally withholding information that could be made public.
