It seems likely that Intel will introduce new six-core processors for laptops, an Intel roadmap reveals this. The roadmap also mentions pending Coffee Lake-E procs, which are Xeon-processors with six for both workstations and laptops. But wait there's more.

German website ComputerBase shared these slides online and reveal a January roadmap including processors such as the Core i7-8850H and the Core i5-8400H for laptops. The first one being hexacore with HyperThreading. Not bad, 6 cores and 12 threads on a laptop eh?

The second one is an i5, that one remains to be quadcore, however, is gets HyperThreading as well. The new procs are to be released somewhere in the second quarter. Also listed are Coffee Lake hexacores for the Xeon series, specifically Xeon workstations. Listed is a Xeon E-2176G for desktops and then a Xeon E-2176M for laptops. You can also spot a Xeon E-2124G, which is a quadcore processor with HyperThreading. 

The roadmap also mentions a threefold of Coffee lake-E, the Core i7-8700T, Core i5-8500T, and Core i3-8100T. These are energy friendly models based on the current desktop line with a T-suffix. The T models get a 35 watt rated TDP, but obviously see a lower base and Turbo clock, but 35 Watts certainly is an impressive value. These processors are to be released in the second quarter, likely April.

One last thing that is interesting to see, the roadmap mentions Cascade Lake SP server processors with eight to twenty cores. Over time these would replace Skylake-SP processors from the Purley platform. Although the beginning of the third quarter is mentioned and likely, it can be seen from the footnotes that the launch window is the second half of 2018. That footnote also applies to desktop Cascade Lake-X. From the looks of it, Cascade Lake CPUs will use the same socket. Have a peek at the slides, there's a whole bunch of them.
