I just got notice that my 1DX has shipped from Crutchfield this afternoon and will be in my hands by early next week! The amazing part is that I just got on Crutchfield's pre-order list on 7/11, and it shipped out today! (Big Thanks to Sephknite for posting about his similar experience with them!).
I am posting this in a couple of threads to both give kudos to Crutchfield for an awesome turn around time and to let the rest of you know that if you are "far back" in a queue at one of the other vendors and really want the camera as fast as possible, you should at least consider getting on the Crutchfield list, as they, like others, don't charge your card until the camera ships. They seem to have a very "short" queue right now (last I read was 8 in line, and now I'm out of the line and so is the guy in front of me).
I had been one of the first to order on Amazon, within two hours of when the camera became available for pre-order on 3/16. Since then, I have not been able to get a bit of information out of Amazon about either where I was in the queue or when they expected to receive a shipment. After receiving my shipping confirmation from Crutchfield, I canceled my Amazon order. Now looking forward to getting the camera in my hands next week.
