FUD Zilla has a couple of tidbits about Intel's Kaby Lake processor. The site writes third generation 14nm architecture will offer more MHz within the same TDP and four additional PCI Express lanes.
Also interesting is Intel Rapid Storage 15, which will introduce support for the Optane drives. The site writes Kaby Lake is expected in Q4 2016, which contradicts yesterday's DigiTimes report which talked about a CES 2017 launch.
Intel Rapid Storage 15 is unique to Kaby Lake-S and the Intel Optane storage technology support. Intel has made us update motherboards to support PCI-e drives and it will do the same with Intel Optane, storage technology that will rely on PCI Express Gen 3.
Intel supplies DDR4-2400 memory support and it plans to teach its graphics a few new tricks. The desktop CPUs are expected in Q4 2016 which is quite late to the game, but better late than never.
