Personally, I think it ll be around before NY. Again, don't base your investment decisions on this, this is just my best guess.
I've read it somewhere that new equipments will be available after September 30. I couldn't find that message again but it was in this forums mining section.
Now you're telling us that they will be around before new year. I don't know what to believe.
I hope it won't be extended and we can see new machines in the market in October.
Anything you read on these forums are nothing more than people's estimations. What Ivan has done is guess when the new machines will be released so that he can base his investment decisions off of something, nothing wrong with that (and he is probably more accurate than most) but the fact of the matter is, is that no one besides Bitmain knows if he is correct, and they aren't telling anybody.
Anything you read on these forums, not from an official Bitmain account, you need to take with a grain of salt.
