Nope. Not ready to upgrade yet. I'll wait another year.

Skylake-X is expected to support 48 PCIe 3.0 lanes for multi-GPU/enthusiast systems with add-on cards for RAID, 10GbE, etc. The Kaby Lake-X PCH itself has 24 PCIe 3.0 lanes, 10 x USB 3.0, and 8 x USB 2.0 - but the price of the Skylake-X is expected to reach around $1500, or more.

I really want to go down to a z series board but the whole 24 pcie lanes kills me. 2x gpu=16 lanes, m.2 ssd=4+16, m.2 wifi=2 ir 4+20 and thats 22-24 lanes leaving you with extra which isnt enough if you want another m.2 or sata express ssd.

With today consumers, especially the ones the z and x series is marketed to, the demand for more and faster storage. Intel nonsense to giving only 20 or 24 pcie lanes. Prosumers thay use z series now need 40 lanes and I feel the professional/extreme users of the x series need 60+. I am no trchnical expert and it might be possible but I feel with technology advancements intel can do this.

I like the idea that Intel is effectively porting i7-7700K into the HEDT platform via the Kaby Lake-X option, siphoning the i7 line up as entirely HEDT territory, as if the i5 unlocked option will vanish (meaning, i5-7600K is the last unlocked i5 in the Z-platform).  It would finally mean that Intel can call HEDT the only platform for overclockers.

It should have happened long ago though, when AMD had nothing for a while, it would have made more sense.  With Zen nearby, I suppose Intel doesn't think they'll lose too many enthusiasts from the i5 on down to AMD.

Intel keep same socket and same chipset 3 years for High End Platform.
I think 10 cores CPU will cost 1500$, but always will be option for around 400$ and 550$.
We could keep same memory on beginning and later to replace. Investment should be only processor if we sell X99 motherboard and CPU.
Or even better investment will be only motherboard when I sell mobo and CPU I will buy successor of i7-6850K. But motherboard is again investment around 450-500$.
Only if Rampage VI Gene show up for 300$ example.

Maybe NVIDIA will go back to 3-Way and 4-Way Graphics Cards in their Next Generation.
Then I would think about a new computer.

there is NO SLi no more or crossfire
 
Developers use mGPU from now on - so you can have as many cards as you want now and intermix them
so anything new(Game wise) does not have SLi settings
 
DX12  uses mGPU
 
why do you want to stay on DX11 and an OS with no support - both from software side(OS and no updates) and driver support on Hardware side?
nevermind that New hardware may not work in Windows 8.1,7 or older and older hardware not not work on 10(not certified or supported)

Kaby Lake X uses 112W TDP for a 4C/8T CPU? 

Keep in mind, TDP is after all just a category, not actual per processor; it gives Intel room to introduce faster SKUs over time without having OEM heatsink companies go out and make new ones every single time for constantly varying TDP values.  More than likely, either the upper boundary from the traditional 95W TDP mark in Client is made for future higher frequency options, or just to allow for the other circuity like more PCIe lanes and quad-channel.
 
 
One need only look at Intel's high-frequency Xeons, regardless of core count, they all have high TDP.
