I submitted a ticket to Bitmain yesterday, and received this email back regarding my submitted ticket :

"With regards to the decrease in the price of our B3 miner, we are presently working on a compensation package for the affected customers. There will be an email sent out to you in the next few days with the details and relevant terms and conditions.

Thank you.

Best Regards,

Bitmain"

We'll see how quickly they come up with a solution, i'm cool with a refund like Chinese customers are getting, that's ideal, or a ~ $600 coupon (but not multiple $100,$200 coupons, that won't cut it)
