Again, secretive at best...scam at worst...no legit demo/3rd party review/etc (at least on the BTC miner, they are pushing)
Likely, IMHO, if LEGIT, they have taken all the pre-order money from the about 3 batches of pre-orders, I'd guess and are mining the hell
out of stuff...(er testing, as they would say)

Not sure about these guys yet, in any way,shape or form.
