(6.6 + 5.5 + 4.6 + 3.9 + 3.3) + (2.8 + 2.4 + 2.0 + 1.7 + 1,4)
= 23.9 + 10.3
= 34.2
So, based on Kano's prediction, 23.9 btc earned in first 3 months, and another 10.3 earned in next 3 months. Total 34.2 btc over next 6 months. Assuming BFL ships 0 units in next 6 months.
Good luck.
Looks like people who are paying 30-40K for Avalon are not calculated risk takers ? But what do I know. Even if btc goes to 1000 usd / btc, someone is better off just holding onto btc itself - not to mention what happens if it goes to usd 10.
16% difficulty rise is not sustainable :-) This calculation predicts difficulty 40M after 6 months and total hashrate around 280-300TH/s. I don't think that will happen.

N.B. the dates are block header times, which can be at most 7200 seconds different to the real time they were found
The current estimate is 16.9565% with 38 blocks to go
Anyway, my point being that a 16% estimate seems far from unlikely considering the first Avalon was 20-Jan and ASICMINER started ~14-Feb?
You really think both Avalon and ASICMINER are going to STOP making ASICs?
It's easier to rise difficulty 16% when the value is 4M than when the value is 8M. And you are claiming difficulty will rise 16% when it's sitting at 34M.
