Op, there is no way you will have KNC in hand by september. November is a more realistic start.
Nor is there any 'way' that difficulty is going to keep rising 62% each month for the next year.
They haven't announced any tape out or anything. No details at all besides some funky diagrams and a FPGA prototype. I'll be god damn surprised if they can and actual deliver anything before November.
Why are you assuming they would have announced their tape out date when it happened? If they say they're on track for September, obviously they must have taped out for now.
Ether they taped out already and are on track for September, or
They taped out in the past and are lying about being on track for September.
But if they're lying, then they could simply lie about having taped out.
