I found this info in their site:
http://www.butterflylabs.com/landing/landing-aw.phpThe BitForce SC chip is now in final stage development. Initial product delivery is scheduled for November, 2012.
However, I'm curious about if they will start shipping in the expected date...
Josh said that, barring any unforseen setbacks, they are still on schedule to deliver in early November. He expects some unforseen setbacks though, and thus tells us to expect delivery in late November.
