It seems Bitmain has made it a habit to perfectly price discriminate amongst their customers. Something economists dream about at night. It is unfair that the second batch has released so soon with such a major reduction of price; destroying the price premium paid by first batch buyers. I do think it'll ultimately be worth it still to be in batch 1 but the risk is high and reward is at most break even.
I sent them a quick email and they replied the following:
"Dear xxxxxxxx,
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,
Valerie
Bitmain"
It seems that they understand their position and are working on a resolution. If more people email them, they will hopefully understand that there are many people dissatisfied. If only a few complaints get through, they may just brush it off or give out a $50-100 coupon that most people won't end up using.
