Sweet. I checked email today to find a message from Amazon:
Hello from Amazon.com.
We are writing about the order you placed on April 16 2008 19:05 PDT
(Order# -------). The item(s) listed below will actually
ship sooner than we originally expected:
"Warhammer Online: Age of Reckoning Collector's Edition [DVD-ROM]"
Estimated arrival date: 09/18/2008
That date jives with what people have been guessing based on the comments made during the explanation from Mythic about the content being cut from the initial release.
