Intel's Alder Lake-S & Rocket Lake-S Desktop CPUs will mark the first major departure from the 14nm process node and the Skylake core architecture, respectively. Intel is expected to ship the latest desktop families by late 2020 and late 2021/early 2022 but it looks like rumors have already started popping up on these chips from Chinese based PTT forums.

Just a few days ago, new details for Intel Alder Lake-S Desktop CPUs leaked out, confirming the use of the LGA 1700 socket. Now some interesting details have been revealed by SharkBay whose leak history is very solid. The details mention that Alder Lake-S CPUs will indeed be supported by a new LGA 1700 socket which will feature two tiers of motherboards.
