How many ASIC miners are in operation?

[SlyFoxy12]

For the first time even the mining pool I use, btcmine.com had what appears to be a ASIC mining running as one user on the top mining board got over 60,000MH/s.

So anyone got a guess how many ASIC devices are out there right now in operation? If you do try and show some working out of how you got to you conclusion

Butterfly Labs are probably using several ASIC devices...

bfl are using avalons in order to prop up their overspending

In wouldn't like to take a guess but its getting harder and harder on my gpu's!

Back in February, before the first ASICMINER chips went into production which was just before the first two Avalon ASICs shipped, there were 22 Thash/s of capacity.   Today there is 85 Thash/s.   Even with the rising exhange rate, there is likely less GPUs mining bitcoins today than in February since there was probably more that defected to Litecoin (due to Litecoin mining being a little more profitable than Bitcoin mining even, over the past couple months) than came online since February.  And almost nobody is buying FPGAs anymore.  So it is probably safe to conclude that about 63 Thashs/s of ASIC mining capacity has come online. 

I don't know the distribution as far as how much is ASICMINER's that they are using for their own mining, versus the shipments of Avalon ASICs and BFLs.

If that capacity were all Avalon ASICs, that 63 Thash/s would represent about a thousand units (and they've not shipped anywhere near that).

I think this springs rally and spike in interest has brought a lot of new GPU miners and they're quite a few people still buying FPGA's.  KNCMiner is about to release a new FPGA - https://www.kncminer.com/products/mars - but yes I don't think most of the new growth was GPU/FPGA but probably a fare bit of it was.
