Then you can make some USB sticks, and make some return for the near future, I'm interested in the miners, but the questios is the cost of the unit.
If the numbering of rigs is consistent with past numbers of rigs by Bitmaintech, the S6 (even number) will be a large form factor with built-in PSU like the S2 and S4 models. The S7 (odd number) will be a similar form factor to the S3 and S5 without PSU.
I would expect the S7 to be approximately 2 TH/s @ .37 watts per GH for a total of 740 watts to make it available for power from a 750 watt [preferably 850 watt] PSU.
I would expect the S6 to be approximately 4 TH/s @ .35 watts per GH for a total of 1,400 watts from a built in PSU that is able to provide 1,600 to 1,800 watts for potential over clocking.
As for the pricing of each rig; only time will tell. The price seems to fluctuate with the price of Bitcoin as of late.

No they haven't. All I've been told is S7 would be announced around July with the new "innovative and competetive chip" and that "right now we have no more info to the public". I would bet the comms are pretty similar to the BM1384, which was identical to the BM1382 as far as I can tell, but the pinouts and packages haven't yet been the same from one chip to the next so I don't expect them to do it again. Hopefully it wouldn't take long to adapt a functional BM1384 board to a BM1386 (or whatever) board if they don't change their IO protocols and voltages, basically just redrawing footprints and rerouting some lines.

well see with the new S7 coming @ 3.5 th in Nov, if it is still over priced , I'll hold out till Dec then sell all my S5 and wait for the new miner at a much reduced price in Jan or Feb, if that wasn't a BS story or even do one of the Group buys but that's not the same as having it in front of me .
I can sell all my S5 right now if want to for 300 to 310 and have them sold in no time till maybe Dec . add a PSU with a break out board Maybe 90 more
.The interesting thing will be once we get Avalon to compare to both of them. I think it will be interesting if it truly does have the underclocking many suspect.
Avalon will do two things push bitmain on efficiency if they are able to beat it by sizeable amount when underclocked. And also a machine to push them a tad on pricing. So really Avalon coming out gives us Hobby and Home miners a lot of hope compared to just 1 single miner being out.
