It hasn't? The full-custom chip Ken a couple of guys Ken hired are supposedly developing is going to use those specs?
I'll answer that for you: no.
Edit:  If the full-custom 28nm is indeed going to be no better than the abborted FPGA copy, the two stealth guys Ken hired are worth exactly as much as their 55nm IP: nothing.

Ken will likely give you a "weekly update" at the end of Q2 to the tune of "we decided to buy a stealth startup with highly valuable IP - all vacuum tube hashing cores!
The chassis are taped out with masking tape, and will be ready Q4.  We also wrote Intellihash that runs on Intellihash, so you can get moar while you get moar!"

You have to be pretty deluded to still take Ken's "weekly updates" seriously.
