Recently a leaked roadmap from Intel showed up on the German website: ComputerBase. This roadmap contains 10 slides with information on what intel has in store for us for the upcoming months. There is some data about server/workstation SKU's and also about the mobile and desktop SKU's.
Server and Workstation Processors
The first few slides about the high performance server/workstation roadmap reveal that Intel will be releasing the Cascade Lake-SP platform in the third quarter of this year and the Coffee Lake-E platform in Q2 of this year. With the release of the Cascade Lake-SP SKU's Intel will be launching their new UPI (Ultra Path Interconnect) technology, which allows up to 3 links per CPU at a speeds of 9.6 and 10.4 GTS (Gigatansfers per second).
Mobile and Desktop Processors
Next up in the leaked slides are the Coffee Lake-S and Coffee Lake-H processor lineups, these stand for the mobile and desktop lineups respectively. From my understanding, some of the desktop processors that Intel planned to release together with these chips, are already on the market like the i7-8700 and the i3-8100. This is because of the successful release of the Ryzen lineup by AMD, pushing up the number of cores in mainstream processors. Intel had to answer that competition and released some of its Coffee Lake desktop processors early ( 5 October 2017), but the upcoming release for the rest of the Coffee Lake mobile and desktop lineup will be in Q2 (probably in April). This includes the i7-8850H a mobile 6-core/12-thread processor with 2.6 GHz base and 4.3 GHz Turbo and the i5-8400H 4cores/8 threads with 2.5 GHz base and 4.2 GHz Turbo, both rated at 45 Watt TDP.

There is also a slide that shows the Coffee Lake-T lineup, these are more power friendly versions of the mainstream desktop processors. They will be rated at 35 Watt TDP and will run on a lower base and Turbo clock.
Here is an overview of the upcoming releases in one slide and a link to the original leaked images.
