AFAIK Cointerra's batch 1 delivery date has always been December.
At some point very soon, mining Bitcoin will become unprofitable overall simply because an essentially fixed number of output Bitcoins are being divided across a larger and larger number of miners.
The only way to mine profitably will be figuring out how to mine both more efficiently and significantly more quickly than the general mining population.
Essentially if you are newly investing in Bitcoin now, you need to believe that (a) the mining solution that you're buying into will be at least an order of magnitude faster than the current generation products, or (b) Bitcoin will increase in value so much that even a small number of Bitcoins will be very valuable.
If this is just another Bitcoin ASIC, it's seems a very risky investment.
If you can't mine profitably, yet believe that the value of a bitcoin will increase, then you're better off just paying money directly for bitcoins rather than inefficiently mining them.
Other Bitcoin companies (KnCMiner, etc) have apparently done 28nm with merely $1-3 million.
Given modern simulators you can simulate the chip pretty completely, synplicity can do the physics simulation of the process to verify geometry I believe.
I have been looking at what it would take to 'mass produce' a simple ARM frame buffer design. There is quite a bit of support out there for "free" (its really back end loaded into the process costs since once you qualify on TSMC it is harder to move to GF and vice versa)
