Regarding the order slow down: A few weeks ago, when this group buy started, there really weren't that many options. However, just in the last few days, a few other alternatives have cropped up, and several seem relatively realistic. I guess those with money to spend are weighing their options between the likes of Steamboat, Terrahash, KnCminer, Bitfury and maybe more projects I'm not aware of. Also, reports suggest at least ONE of BFLs 60hg/s boxes have shipped (out of how many thousands ordered?), so there is movement in that camp, too. COuld be part of the explanation.
