https://store.mineority.io/product/fpga/Kristy-Leigh Minehan (aka OhGodAGirl) has teamed up with GPUHoarder and there is something like 1900+ FPGAs available. At least this is what her store counter says

I believe she mentioned that Mineority had acquired 2000 units to make available to the public or to run them in-house. Don't quote me, head over to their site and read for yourself.
So that's 5000 units + 2000 units for a total of 7000 units going be from xilinx that is going to be on hashing? Wonder how many more there are... hashrates seems like it's going be saturated. Considering some bought from xilinx too directly from whitefire thread.
The 2000 units she bought were what was available after the direct sales closed.
There are only 5000 available total, for 2019. Most of the xilinx model number units (vcu1525) were not in stock at the distributors, as they (up until this) were generally used for prototyping and development, not as an end product.
It will be interesting to see where the hash rate goes, since these can do many algorithims depending on what bitfile is loaded.
