While I'm hoping for a release tomorrow, because then I have most of the weekend to play with a new toy, it is probably going to be the 1st or the 8th. Software retail releases are, for whatever reason, done on Tuesday. Maybe audio software is different, but that is when games n' such release at retailers in the US. I don't know why they like Tuesday, but they do.
Developers like Cakewalk go along with it, of course, because they need the chains happy. While Digital Distribution is growing, you are still DOA if stores don't carry your stuff.
