Yes, but then the 14 and 16 cores are currently vapourware too. Somehow I had though that Xeon E7 (where these 14/16/18 cores come from) was a different socket with more pins. But no, their current max core count is the Xeon E7-8894 v4 (24 cores, 2.4GHz base with 3.4 single core turbo with a 165W TDP). So really, turning the upcoming Skylake Xeon E7 18-core into a Skylake-X basically involves disabling EEC and calling it a day? In which case, the Threadripper announcements* to October is probably enough time.
*or the first rumours since Intel must presumably have some info about what the mobo manufacturers have planned)

But they are on the same socket.
Now what you might mean as that those Kabylake-X chips are LGA1151 chips routed into the LGA2066 socket in that they don't use the full facilities. Which is true. But Kabylake-X has 2066 pins, normal Skylake/Kabylake has 1151 pins.

It's a Kaby Lake with a speed bump slapped into the LGA2066 package. X299 is all one socket, don't confuse the packaging with the capability of the chips. The problems the mobo manufacturers have is designing a board that can support 16-44 PCIe lanes, dual channel / quad channel memory (so depending on cpu some memory slots are disabled). Essentially it's a highly fragmented platform. I suggest you watch the video linked.
Re: Intel announces Core-X series CPU availability
I stand corrected - turns out expecting any sense from intel is a mistake. The datasheet shows the bottom two are on the big socket. How they expect this to compete with ryzen is beyond me - the small socket intel boards are already pricey, putting the refresh into the bigger socket will only make this worse (previously an 1800X was a big more expensive than the 7700K IIRC, with this the refresh will have to compete at the same price or more than the 1800X). It's fantastically stupid - not only is there less PCI lanes, there's less extra PCI lanes to hang hard drives off - so some SATA slots just won't work when you get a cheap CPU, there's no way this can confuse consumers.
