With respect to the speculation above we sold out of Neptune's last night.
Can you post how many Neptunes are sold in all batches? Just trying to calculate PHs when they eventually come online.
If each batch is 1200 would that be about 1.5 billion difficulty added for all 3 shipped is that right?
Yes, that's about right, (in THs):
https://www.google.rs/search?q=1200+*+3+*+310,800 THs = 1,508,742,620 difficulty. That's in case each Neptune is 3 THs, add expected overclocking %.
Edit:
Waiting for Bitcoinorama confirmation there are 3 X 1200 Neptunes sold.
