We saw maybe 100-200 surface on Taobao, so my guess is the "small batch" are those devices but reflashed back to Sailfish. From what we've seen this means they will be 32gb devices, not the 64gb ones.

This makes a reasonable amount of sense, because the first wave was likely a final pre-production batch to ensure quality before running 1000+ devices off. So this batch will be the same thing but for the 32gb variant.

I find it unlikely that a new batch would actually get manufactured, only to stop after a few hundred. Clearly relations between the manufacturer and Jolla have broken down and so making more tablets would require finding a new manufacturer and starting the process all over again.
