What I remember about the original release of the game was that the DVD had the game, but it was encrypted. You could pre-load it onto your machine, and when it released, they'd provide the key over Steam, and the game would decrypt. Or maybe I'm confusing that with a pre-release encrypted file that you could download ahead of time, to save the download later. I'll have to look at my disks when I get home; I was pretty sure that they had the full data for the game on them.
