Loanranger has stated that references to the "flagship processor" can only refer to P3. Even I think that is a leap of a conclusion. It could easily refer to the P3 design, which P4 and P5 have presumably copied, rather than the physical processor.
But we still have no idea if they have made that design work well enough to make sales a slam dunk.
I suspect sales will be difficult and no where near the $8 million asking price until they can prove they are worth that much.
