e14/Embest have been building these for quite some time, but only selling to 
China

The creation date on this article is Apr 18, 2013:

Now it may be that they're tuning a process on a new production line that's 
been spun up to meet demand, but that's no reason to think they don't know what 
they're doing. It is obviously a different process to CircuitCo as some of your 
earlier observations show. We also don't know how many of these boards embest 
have already sold in China in the last year.

Received one today, given that it has an AM3358 and the R8/R9 change then it 
appears to be a RevB equivalent. Older version of Angstrom, but that'll be 
getting wiped in the next few mins anyway.
Different pre-installed image could certainly be a confusing problem for some 
people though.

With 25 years in the electronics subcontract manufacturing business behind me, 
I personally have no concerns about the quality. I suspect e14 don't either or 
they're unlikely to have engaged in wide distribution of a board that they'll 
be directly responsible for. Not like they can RMA these back to CircuitCo 
after all.
