Butterfly Labs has shipped a couple of 60GH/s miners to the guys at Wired Magazine, there is also rumor that they have shipped devices to a couple of civilians. There is an article on Wired.

The hash rate will not be effected by 60GH/s miner sales and I doubt the hash rate will rise to far with only a few hundred 1500GH/s miners being released. Just wait and see what happens, nobody can be 100% of what is going to happen as it is a world first - if their devices work as planned. I hope that the ones that get their devices first make the most as I have ordered 3 mini-rigs (stupid idea - I am currently hiding from my bank) and am on the list of a June shipment.
