They've stated they are going to start shipping Jalapeno's next week and maybe even a few to developers this week.  As that is the only model they have boards for that they can power ATM.  They state they will have the boards for the SC soon and they should start start shipping in a couple of weeks IIRC.  The chips are now rated to use a lot more electricity.  As Josh@BFL quoted us $20 a month for hosting each SC I don't know if he has revised this figure.  He has not stated so or contacted me about it.
