Alpha = $590 (with free upgrade to Beta Bold)
Beta = $590 (pre-orders start in second half 2017)
Beta Bold = $790+ (pre-orders start in second half 2017)
Demo Pair = $169 (I assume this is Alpha as well)
So, the Alpha model pretty much cost 6 to 7 times about $170 while Beta Bold cost about $790+?
By the way, when will Beta pre-order be opened?
