One thing I think we should consider is that Disney is now involved with the production of Xwing. The new core set came out with no knowledge of it's existence ecxecpt for the mystery SKU's. I think that at least the film/cartoon ships will come out on target, if not all of the next waves. I don't take sides on the whole Disney thing, but they do know how to capitalize on buzz and their manufacturing power is tremendous.
TL;DR - The dates are right because...Disney.
