After reading this and it being a quiet day at work I thought I'd give calling Subaru of America a try to see if they could look me up and find a VON for me.
I ordered my 2013 WRX Limited w/nav and short throw/auto dim mirror on 8/11/12 (Probably officially went in on the 15th) and didn't really expect to have a VON number yet givin only 2 weeks but he was able to look it up and give it to me. It was however too early for him to give me an ETA. But he did say in a general sense 10-12 weeks.
And living in Boston is helpful as the Subaru's port about 1 mile from my house and I drive over the bridge and look down on them in the car port every day on the way to work. So there won't be much extra time tacked onto the delivery date to pickup.
