I saw a while back that people who ordered 520GH/s models got upgraded to 1.2TH/s models. I am wondering; did customers who ordered 1.2TH/a models get an upgrade? Also, when are they supposed to ship? I believe the last supposed delivery window has passed, and I have not received mine so I am just curious. Lastly, if possible I would like to know the status of my order which is #847. Thank you.
