I guess I hit the upgrade bottleneck. I shipped mine to them last Monday the 3rd. Although FedEx delivered it on the 4th to them, they didn't claim to receive it until the 5th. Online status showed "RMA Processed" on the 6th, and has "This device has shipped or is in the process of being shipped back to you. If no tracking information is available, please check back at a later time to allow our system time to update..." at the top of the status still. Called yesterday and all they would say is that I should receive it by the 12th. We'll see if they really ship it back today.
I'm curious if everyone shipped theirs to Elgin, IL, or if they have multiple upgrade locations. If they do have multiple locations, it would be interesting to see if certain ones are slower than others.
