Well technically the Zen 4 mobile parts have been announced, as AMD officially published their 2023 mobile lineup a couple weeks ago: https://community.amd.com/t5/corporate/announcing-new-model-...

Here's the segmentation:

* Mendocino (Ryzen 7020 Series) - Everyday Computing

* Barcelo-R (Ryzen 7030 Series) - Mainstream Thin & Light

* Rembrandt-R (Ryzen 7035 Series) - Premium Thin & Light

* Phoenix Point (Ryzen 7040 Series) - Elite Ultrathin

* Dragon Range (Ryzen 7045 Series) - Extreme Gaming & Creator

But the product "launch" will, as you mention, likely take place at CES next year.
