Yep, I think that the 40GH/S will be the new 1 Gh/s Since 1300.00 is close to what it costs to purchase a 1 GH/S today and in october a BFL sc single. The ones that will make out well (If they exist and ship on time) are the early receivers, obv. But, eventually, what you can make today with 1 GH/s will be the same with a 40 GH/S in the near future.. Dollar for dollar, I think that they will be very close as it is today...
Just thinking out loud...
Actually, $750 worth of GPU will get you 1GH (One 7970 can do 600Mh and they retail for about ~$450.) which works out to 1.3MHs/$
$600 worth of Butterfly labs will get you ~830MHs (BFL Single) which works out to 1.38MHs/$
$15295 worth of Butterfly labs will get you ~25GHs (BFL Mini Rig) which works out to 1.63MHs/$
The BFL Jalapeno claims 3500MH/s for $149 which works out to 23.5Mhs/$. Four times the performance for one quarter of the price.
If the BFL Single has its FPGA core(s) running at 200Mhz, they only need to boost that to 800Mhz (or use 4 ASICs in parallel) which is feasible.
There are companies which specialize in converting FPGA designs to ASICs and then sharing space on wafers with other customers in order to produce small batch sizes economically. It seems feasible that the COGs on the Jalapeno ASIC(s) could be lower than $149.
All that being said, I think 16GH/s will be the new 1GH/s.
