Thing is, Miners batch 3 by avalon, is a big pain in the ass for them. Miners for sure takes longer to make than shipping tens of thousands of chips (and imagine having direct consumer support for a miner, instead of having one client, purchasing 10.000 chips and supporting of that instead). I am sure this is the last batch of miners they will ever ship (aside from the very clever Blockerupter USB that will never generate any profit to anyone but asicminer who are avalon or correct me if im wrong here).
That being said, i dont think they are prioritising one or the others. Factories making chips, still produce chips, and factories making boards and cases, are still doing that aswell.
It is however odd, that it takes them so long to finalize the batch 3 avalon miners..
To clarify, i dont think staff busy making miners, would be occupied in making chips and packing them in a batch of 10.000 or vice versa.
