1) The average hashing power per chip has been beefed up significantly from our estimated 300Khs per chip to 800Khs per chip and thereby reducing the number of chips required to reach the required hashes.
Someone already asked about this, but I didn't see an answer..
If the pre-order price was calculated for 17(?) chips (300kH/s * 17 = 5.1MH/s), why won't you keep the 17 chips and make the units faster than estimated?
