So just looking at the materials involved... what drives the price and how long before we see competition bringing lower prices?  I imagine R&D, labor/personnel, maybe some factor for intellectual property is driving the current price.  I also seem to recall somewhere that current prices are very low as it is with sales being made near cost.  Then again, cost for that initial R&D can be quite high and cost for competitors -might- be much lower. The m.2 technology is well known with various articles on the topic.  My guess is more pressure from Samsung and companies like Halong...  Bitmain may remain in their comfort zone... or not.
