No, they've been very closed about that - but so have ALL of the other miner manufacturers for ANY ASIC-based mining machines.



 The iBeLinks aren't going to achieve ROI in 2 months - it's already been almost that long since they were sold out and they don't appear to have shipped a significant number of them yet (and if they have shipped any it was to the folks that ordered back in May or so when they first went on pre-order).

 They *might* achieve ROI in 2 months of OPERATION if they start arriving before the end of the July, but when it takes someone 2-3 months to even GET the miner that's NOT a "2 month ROI".

 They're also going to bump the total network hashrate up a LOT before Bitmain or Innosilicon even START shipping the D3 / A5 at all, which will make it take longer for THOSE miners to achieve ROI - and THOSE miners are looking at 2 months or more of "pre-order delay" before THEY start shipping, presuming Bitmain and Innosilicon meet their announced shipping dates (Bitmain has a pretty good record there, Innosilicon is mixed).
