That is the problem, these guys can say they will release on a date, and then later change the delivery schedule. If it was a more established company I would prob vote for it, but I am not too sure with these guys.
Don't forget that the more we mine now, the more money we have to invest in future equipment. Money sitting in this guy's bank account loses value over time.
Does anyone honestly believe that these ASIC manufacturers will release machines on time?
