There's no new Optane hardware yet, just a renewed attempt to push Optane caching for mobile use. Intel plans to release cache-sized Optane SSDs that have low power idle states, to replace last year's 16GB and 32GB modules that idle at 1W.
Intel is also updating their Windows drivers to enable Optane caching of non-boot drives. For the past year, Optane Memory caching has only been usable for the boot volume. This driver update should be available for both the new platforms and for all existing Kaby Lake platforms that support the original Optane Memory implementation, since there's no motherboard firmware functionality that needs to be updated for non-boot volumes.
