Just got an email from Blokforge, a US distributor:
*Please be aware that the Avalon 761 is for the China market only and will not be the next generation of miner in the US. Any changes or updates will be sent out via our newsletter and posted in our forum at BLOKFORGE.COM.
Looks like the A8 will be the next device available outside of China. I was advised that we would have more details next week regarding pricing and specs.
Cheers.
