If a dealer doesn't have any allocations left then they will gladly take your order but won't be able to submit it all the way. As far as when you could get the car at this time no one really knows. Figure something like 13,000+ pre-orders and I've heard numbers between 5,000 - 6,000 GM dealers who are all getting a V6 car. If the plant can produce 450 cars a day then it will be just over 42 working days until the pre-orders and dealer cars are done. Reality says it will be somewhat longer because the plant has to get up to full speed.
