What PCIe x8 SSD controllers are on the way?

[cbn]

So for all I can find are these four made by Microsemi:

PM8609 NVMe2032
PM8607 NVMe2016
PM8604 NVMe1032
PM8602 NVMe1016

These are PCIe 3.0 x 8 with either 16 or 32 channels.

Also how about unlocked PCIe x8 cards with PLX bridge chip that can mount multiple PCIe x4 M.2 SSD?
