I'm guessing Bitmain literally means before September ends, like literally shipping on the 31st.
My uneducated guess is they're waiting for any BTC price pump up, so they can better profit on the S4 sales, and mitigate shipping costs.
No, they said on twitter and also on their website "THIS WEEK".
can you point me to the official twitter feed of bitmain?
thanks
Nothing on twitter about it anymore than on the forums here.
Thinking about it, does anyone have any idea on the ROI if the S4 comes out at $1500? Rumors have been circulating that
the ROI numbers would have you running well outside 6 months before a profit can be had and that's only if the difficulty rate
stays at an average of 20% a month which, I would now doubt, especially with Bitmain running up another 7PH/s in over 4300
S2 machines that came online. (I can't even imagine seeing 4300 machines in a room just sitting there let alone all hooked up
and hashing away!) China Power must have substations sitting on Bitmains roof!!! LOL

If you have to ask these questions, STAY AWAY FROM MINING!

I don't think you understood the question. I have a farm with 79 Terrahashs of Bitmain and Avalon equipment. I wanted to
know if anyone, off the top of their head, has done the calculations for the ROI on ONLY the S4 based on rumored price
and the crap performance of the coins value over the last month (and of course taking into consideration the difficulty swings).
There are too many conflicting stories out there from people that don't have a clue about much else than sitting at home with
their three S1's just "burn'n up" the pool they're in and thinking they have all the answers. (I haven't even met people with
more than I have with all the answers!)
