Yes that was my presumption as you posted your reply shortly under my post. Anyway you are right. It doesn't matter
Also as to where all the new rigs are coming from:
BITMAIN shipped out a thousand or two of their AntMiners, they are going to be shipping out even more USB miners
btmine has some new ones in a groupbuy
people are still making rigs with the chips they bought.
Bitfury has miners in stock
ASICMiner is doing their thing and constantly adding to their own farm.
