Contrary to what everyone else is saying, I truly think this is on a fast-track.
Someone else already used this analogy earlier this week, but it fits:
In "Return of the Jedi," when questioned on having the new Death Star finished in time to battle the incoming force, the Emperor proclaimed, "Now, witness the power of this fully-operational battle station!"
In any event, I think we are still looking at a September time-frame.
