Presumably, they started development on this 6 months ago.  This will be the 2nd round of asics being produced.  They have to be getting better at this game by now with more industry contacts and suppliers.  Now they have 1 product line instead of 4 greatly simplifying the production.  They are going after the higher end guys who are willing to make a business out of this.  Its got to be annoying to sit and listen to some guy who ordered a 5gh miner for $300 bitching about when his shit is going to be there screaming SCAMMERS all day. 

I'll admit this came sooner then what I would have expected. 

You now have 3 choices.  1) Double Down 2) Go long, 3) Cry Moar.  90% of the people in the forum have chosen option 3.

Anyone who is serious will choose option 1.  I doubt many will choose option 2.
