I ordered mine from the RR EU store and on the order page it said:
"** Due to the high quality of the box set, it will be shipped 4-5 weeks after release, but to ensure you still have the music a digital copy of the album will be sent to you on the Friday before release."
When I got the mail with the digital download link it said that it would be sent within two weeks... So for me that's an improvement over what I expected.
