So is there an official release date, or even close to a release date?

Amazon says sometime in August

There's a good chance there'll be a few copies at GenCon, with the actual release being somewhere around october - that's what they did with Rogue Trader and Deathwatch at least.

Forget Amazon when it comes to RPG release dates.

They (Ross I think) pretty much confirmed that they were bringing Black Crusade to Gencon (in agust) this year in the interview that's linked in one of the posts here. They didn't give a specific release date however.

Thanks, it is at least something.
