Thanks for the reply, I'm certainly not expecting 100MH/s : 1$ for the market price, as BFL's alleged SC Single is only 30MH/s : 1$. While it's great news to hear that can be done, I'd say anything around 20+ MH/s : 1$ market price would be an excellent BFL ASIC competitor.
As I said, <1$ per 100MH/s is the estimation of cost. The market price for selling will probably be higher.
Any chance there is a CAD drawing of the Block Erupter yet?

That would certainly be more than BFL has managed to come up with yet.
Currently what we have are netlist files and back-end results in various stages. They haven't been visualized yet. But it's possible that we come up with tangible pictures to share before the production.
