We are busy on putting part of the first order of 1200T to the farm. We just added 10 more miners to the farm today: http://eligius.st/~wizkid057/newstats/userstats.php/1swrtyBsp9odruX65upeyubAVSAyggh78

The price will be updated when we start to accept orders (probably in two weeks), could be around 5.5k-6k depending on our cost and the price of bitcoin.

Bitmine and Innosilicon worked together to produce the chips, so both of them have rights to produce/resell the chips.
