I seriously doubt there will be a diff climb because of these miners.  They aren't more efficient than GPU's.  As a matter of fact rigs running 1080ti's with the Eth Enlargement Pill are probably quite a bit more efficient and hash better than these by a decent margin.   I don't have any 1080ti rigs running to run the numbers, but at initial glance that would appear to be the case.  I am sure someone who is running those rigs can chime in and tell us their experience. 

So I don't think these rigs are going to do much if anything on the ETH network unless they are selling them like gangbusters which from looking at the batch number increase, but the dates stay the same it would imply they may not be selling as fast as Bitmain had hoped.  I think the fear of ASIC's can be warranted when the technology disrupts the status quo, but in this case it didn't as these did not change the hash rates or economic factors for mining Ethash.  I don't see how the fear in this case is warranted. 

btw, I haven't gotten my shipping notice yet for mine.
