Thanks, you're right.  The current BFL numbers were calculated before they got their chips back, using the 7.5GH/s/chip they were quoting at the time.  I have updated their numbers.  Thanks!

Edit: this puts bitfury back on top by a hair.  I think it's really interesting how close the numbers for the three different first-gen custom chips are (BFL, bitfury, and Avalon) despite a wide range of fabrication processes -- especially compared to the huge difference between them and the FPGAs/GPUs.  I think that partially validates the hash-meters/sec metric.
