We're in no position to speak positively about JBI's "flagship" processor design or at least the design they've settled on now that they've run out of money and are forced to admit they're out of the grey area of R&D.
Processor 3 has been live for 9 months and they've disappeared... literally.
How much Money has been spent on developing the processors? I think it is a low fraction of the Money spent since the company was established. For instance a good deal of money was wasted on two acquisitions. John seems to have been duped in this case whereas he appears to have duped others when it comes to financing his company.
