Supermicro's just posted their new range of AMD servers and motherboards:
Supermicro AMD EPYC™ Processor-based Solutions | AMD Solution | Products - Super Micro Computer, Inc.
Assuming the numbers and prices end up looking good and teething problems remain minimal, there's a crapton of IO available here. The no-details-yet H11SSL range of single socket boards look ideal for workstation and SME servers that don't need a great deal of compute, but come with three 16x and three 8x PCIe 3.0 lanes (for presumably not a huge amount of money) - 72 lanes in total which is a pretty impressive amount of IO. Interesting times.
