As quoted from chinese forum the price WILL BE between 88-115 BTC.
So with BFL on the way it wont be profitable. Better to invest in BTC.
Funny thing is that they say 90 btc is estimated on "reasonably expected ROI". Yeah, "reasonably expected" if BFL is a scam, no other player delivers ANY ASIC in 2013, and ASICminer does not deploy any more THs.
Even if all the above turns out to be true and AVALON is the only company deploying ASICs from now on, the ROI will be in aprox. 3 months. And believing that all the points above are true is a +5.000usd bet I'm not willing to take.
