You may be right about that.  Let's review.  The S2 was released in Apr of 2014, right?  For a cost of around $4,000.  That's Apr.  Of this same year.  As in 6 months ago.  And now Bitmain seems to have decided it's not worth their time/effort to release updates for a product that's less than 1 year old.  So the simple question is if Bitmain doesn't think their products are worth supporting six months after they were released why should anyone buy their products?  You're taking a serious risk buying anything from Bitmain.  They won't get any more of my money.
