What is Intel doing about AMD RyZen?

In the gaming desktop market, Intel shouldn't be too worried yet, as 8core/16thread RyZen processors aren't good at high FPS (75+ FPS) games in 1080p, while Intel's Kaby Lake Core i7-7700K processors have a better IPC, higher frequency and about 30% more FPS in most games at 1080p.
The answer is Kaby Lake X, with a twist. So Intel Core i5-7640K and Core i7-7740K will be launched on a new socket type called LGA 2066, with Intel X299 chipset. This new platform will support up to 44 PCI-Express 3.0 lanes and 4 memory channels, but these Quad Core Kaby Lake X processors will only be able to use half of that (2 memory channels and 20-28 PCI-Express lanes).

Another interesting move, made by Intel, is the introduction of a new server platform with a huge LGA 3647 socket, which will run Xeons with many many cores.
It's a bit odd, that the press didn't really report on these platform, as everyone was focused on AMD RyZen. Speaking of which, AMD is also preparing 12-32 core processors for the workstation and server markets. These new processors will offer a far better value for the price, but won't fit in AM4 sockets, unfortunately. These new chips will require AM44 socket motherboards with X390 or X399 chipset (presumably the first is single socket and second is multi socket), so it seems that AMD is also going in that direction, with larger sockets.
This diagram was obtained from unknown sources. Presumably it's an ASUS motherboard, but nobody can confirm or deny it, as usual ...
This is the chipset diagram, and it looks extremely promising, as it features 44 PCI-Express 3.0 lanes and 4 memory channels, although they are marked in a strange way: MC1, MC2, MC1, MC2 ... that should mean 4 channels.
