I will be optimistic and say that Neptune will be 5TH/s.
For 0.10BTC a day we need a difficulty of 25 billion.
25 billion difficulty = 179PH/s = 35800 Neptunes.
With batches of 1200 that seems highly unlikely even with all the competition around.
I wouldn't count on Neptunes being 5 TH/s. Cooling that beast would be crazy.
I wouldn't count on HashFast not shipping. And Cointerra not shipping. And Black Arrow not shipping. And BitMine not shipping. And BFL not ship...wait, you can count on BFL not shipping.
