Over on Medium, Intel posted a piece that mentioned Rocket Lake. John Bonini is Intel’s VP and GM of Client Computing Group Desktop, Workstations and Gaming. 

“I’m also happy to confirm that the next generation 11th Gen Intel Core desktop processors (codenamed “Rocket Lake”) is coming in the first quarter of 2021 and will provide support for PCIe 4.0. It’ll be another fantastic processor for gaming, and we’re excited to disclose more details in the near future.”   – John Bonini

Rather than speculate on the platform, it does seem timely as AMD is expected to release the new Ryzen processors in a day. Most likely the introduction will be in March 2021.
