I expect to have a Nezha before the end of the month. I got in an early-bird order on Indiegogo. I've been using one in Beijing via SSH (thanks to RVBoards) for the last three weeks.
I've already have a BeagleV beta board for almost four weeks I think.
I'm expecting a HiFive Unmatched in very early June -- SiFive report that the boards are currently en route from the factory to Mouser.
Shit's getting real fast.
