Currently were looking at 450 Th/sec that we expect to enter the network between September and the end of October, Cole predicts. That will mean substantially increased difficulty as more miners come onstream.

http://www.coindesk.com/a-look-inside-kncminer/That was back when they thought their products were 400GH. So now that they might be 500GH? Make it closer to 600TH I think?
If they had sold 450 TH/s of 400GH/s miners that then turn out to be 600GH/s miners, that make the total ~675TH/s - a long way from 2PH/s still.
That article was written back in June. I imagine their sales are higher now, especially after all the BFL fails...
Might be possible that this numbers is only the hashrate of the first 890 orders..as it would result in 450TH/s divided by 0,4 TH/s = 1125 Jupiters
*edit:
..and 890 is only day1+day2 as far as I know...?
