Look, take it with a healthy serving of salt, but I have heard a number of things from some fairly reputable bus-drivers that definitely have me curious.
The main gist of what I've heard being that Universal has bought out the contract with Warner Bros/JK that had the park legally bound to only open if Battle at the Ministry was in operation. The idea being that Universal can now legally launch Epic without Battle being open to the public, giving them a few extra months to work out kinks. Think SW:GE and Rise.
It's not something I'm really all too thrilled about, but to me it at least seems plausible. Maybe someone here has heard similar, or completely opposite.
