Based on Bitmains D3 at $2699 and cracking along at 15Ghz
$2699 / 15 GHz = $179.93 per GHz
So 179.93 x (Baikals 2GHz) means the Baikal price should be $359 per unit if you ignore power and algo differences
Getting the Baikals early doesnt outrun the price difference if you have to wait for the Bitmain D3
I'd say this is a multi-algo play. Giant plus is the only new asic that can mine x13 x14 x15 quark and qubit. I'd recommend researching these other algos (and their corresponding coins) to see if that advantage is worth the reduced hashrate.
Diversity may be important in this brave new world of x11 Asics...
