I think that up to now JBII has not focused on production or cashflow but on improving the hardware. The explanation is that John has been focussing on the long term, which I agree with. The most important result of this is that the output has been doubled which in my view more than justifies a delay of a few months.
I see no reason at all to question the basic profitability of JBII. However, overhead seems to be increasing fast in preparating for fast growth in the future. It may therefore take more processors running to achieve profitability than half year ago. With a gross profit margin of almost 90 % and production set to increase by leaps and bounds I see no good reason that profitability will soon be achieved.
