From what I understand, they are only producing so many cars, and the number/type of orders has little or no bearing on the number they produce. So it is possible that they could fulfill all the orders for the 2013MY and your order could spill over into a 2014MY. At least that's how it was explained to me; perhaps you can confirm or deny that. I had a lengthy conversation with the SoNE rep who basically said they build cars in batches and fulfill the orders first, but just because there is an order, doesn't mean that they will build the car.
I ordered my GBS Limited 6MT on Feb 21st and they haven't even put it in my dealer's allocation, let alone build it. I also have a customer who ordered a '13 WRX Limited with navi around the same time, and they've allocated but not built his yet, but we've gotten a WRB WRX Limited and CBS BRZ Limited during the time our cars were ordered, because that's apparently what they already built.
