I know that Bitmain's pricing history would make you think a price drop is right around the corner, but why would they do something like that when there is no REAL competitors at the moment?

Their pricing model has been to lower prices to keep competitive with other manufacturers.
They dropped the price of the S7 when Bitfurry looked like something that would encroach on their market share.
As it stands there is no one close to having a market ready product. On top of that, what real gains do you expect from the next line of miners? 14nm?? 10nm?? In my option that is still way off.

Bottom line is, I wouldn't expect a price drop this time around until something forces Bitmain's hand.
It's just business.
