Jeff Thomas at Sage Engineering wrote a blog post yesterday on the new Intel Skylake board.
(Sage is an open source-friendly IBV, they focus on coreboot and Chrome OS, and know a lot more about AMD platforms than I know. Jeff is an active blogger, and a good source of industry news.)
On a somewhat related note, from an open source OS-level perspective, Skylake has graphics that require non-free firmware blobs, which is IMO unfortunate:
