full custom, so is our 3rd gen.
Speaking of which, is that still Pickaxe (80/20 custom/auto), or do I need to be adding a line to the wiki?
On the BitFury end.. as 16nm is claimed to have taped out, is there any chance we can prise some more solid info on the 28nm chip?

It's pipelined (unrolled) full custom.
BitFury 16nm was indeed tapedout.
I don't believe they'll release any info on their 28nm, seems they're following "The Art of War"
