Hey Bitmain!  Since most of the world isn't going to buy your S4 at that price, do you have any plans to offer more S1 upgrade kits? 

Did you discontinue them or just sell out?  Can't seem to find out from anyone if you expect to have them available again.  Lots of S1's out there that we could upgrade in order to mine coins to buy your S4 (after you lower the price, of course!).  So you see, leaving us with S1's and the rolling batches of S3's that are bought more often to be re-sold than used only hurts your S4 sales.  Kit me and make me happy.
