Based on the numbers I can find, the current total hash rate of the network is around 6000Ths. KnC is building 1200 Neptunes to be released in first or second quarter 2014 each with 3 Ths for a total of 3600 Ths to be added to the network. If my calcs are correct that means almost a doubling of the hash rate from one manufacturer and one batch.

Do everyone's estimates of 5 or so billion difficulty by March 1 take that into account?
