SO if i understand this right you will be charged the diffidence in the going price once it's ready to ship, so you get fuck kind of any way and end up paying out the ass for the A4 + ? ..

or they will upgrade you to the A4 + at the A4 price you signed up for to start with, i hope you guys get that which they should do. but don't count on it there greedily like the rest ..

For example, you preordered A4 280Mhs miner totally N dollars, as we upgraded to A4+ with 550Mhs, your total payment will be (550/280)*N dollars. Your deposit will count towards the total payment.

the A4 should have been the A4 + to start with .I saw that coming and kind of hinted about it in another post .. the A4 was suppose to sell as a A4 + or at  A4 + speeds, to me that was meant to happen so they could make more and they knew bitmain was coming out with a L3 and L3 + by a comment they made in a post when they sold all the A4 stock cheap.

We are being told that they will offer to let you upgrade to the A4+ if you are willing to pay the difference.  However you may want to contact them to get that in writing from them. 

I will let them know about this thread and see if they want to chime in on how this will work.  The email I have from them states that is how it will work, but I would rather you hear it from them.

I am in for 3 more if its at $2500 each. I am in USA
