if theyre testing a bunch of chips it would make sense that they might be changing the clockspeeds/monitoring cooling and looking at all sorts of metrics, as well as possibly testing drivers and programs because the other asics came online with cgminer supporting them... that wont be the case for scrypt asic
It's bloody ASICs in china guys... Do your research.
who know's what is really going on. I thought i read previously that they had a farm of 3x290 rigs, so whatever.
