Recent GAW announcements:
- the Vaultbreaker aka Titan Killer 750 MH/s Scrypt ASIC batch 1 will be hosted soon-ish (?) on ZenCloud, including the ones purchased for shipping. It will not be able to use The Most Profitable Pool In The World (ZenPool) but will keep it's original hosting cost ($3.67 per day).
- alternatively said Vaultbreaker can be converted to Hashlets. This option will allow to use ZenPool, but will incur the Hashlet maintenance fee ($60 per day), which is significantly higher than Vaulbreaker's fee.
- same options are available to Vaultbreaker mini (375 MH/s) batch 1, but do not apply to VB / VB mini batch 2. Batch 2 options will be announced later.
- Hashlet price will be increased "tomorrow", not sure if that means Sunday or Monday. The new price is not known yet.
Other observations:
In the announcements GAW CEO mentioned "A2" and "proprietary Hashlet hardware" but did not mention Zeus hardware seen in the warehouse pictures.
ZenPool has grown by another 50 GH/s in the last few hours -

You are right, that is a warehouse, not a real mining farm and those are Zeus chip based miners, not 28nm A2. In the other photo they showed long time ago (the tiny basement mining farm), there were some A2 miners. But GAW has not ordered from Innosilicon for a long time (nor Gridseed, nor Zeus).
