That is complete bullshit. Gen 4 tape-out occurred on September 16 and FC is expecting Gen 4 chips for testing around December 16. That's less than 2 months from now. Mass-production of Gen 4 is expected to occur in February/March. That's 4 months for mass production of gen 4, not 8.
Gen 3 tape-out happened early February. Real world availability is only happening around now; ~8 months later.
Do you honestly think that the share price will not rise will in December if the chips pass the tests or that it wont rise with the mass production of gen 4?
Both bitfury and spondoolies expect their next gen 28nm miners this year, one with 0.2J/Gh (0.1J next year) the other 0.1J/GH at the wall. AM is aiming for 0.22-0.34J/GH (and that appears to be for the chip alone) at least one quarter later. Even if AM is on time and on spec for a change, I wouldnt get too excited if the network is pushing through 1EH by that time at todays exchange rate.
