I think they are M/Hash not G/Hash, and judging from the numbers they look like they could be Jalapenos.
People seem to forget the fact that ASICs themselves are not only for Bitcoins nor are they owned exclusively by butterflylabs. This could easily be another company etc.
What bitcoin speed calc lists their numbers in kH/s? I would assume they're measuring in MH/s, in which each working would be close to 50GH/s.
Their 10million and 17million shares would seem to agree with me, as it wouldn't take long to get those numbers.
