It's an incredibly bold statement to try and achieve up to 20% of the total network hashrate. If they really used the miners they're now selling, they'd need over 20000 of them. Are they going to use those machines or are they using other ones? I don't really know whether their immersion plans have become reality already... What do you think?
Ambitious but hardly impossible. I think even Butterfly Labs could build 20,000 devices in 5 months (assuming you gave them some functioning chips). Friedcat has most of the short order high tech manufacturing capacity that the world has to offer right in his neighboorhood. He could contract with Foxconn and have those built in literally days if he had all the parts ready. most of us in the rest of the world can't wrap our heads around how fast the Chinese can turn product. It is really mind boggling if you look into it a little.
