Hi,
Intel had announced plans to launch its first PCIe 5.0-based products in the second half of 2022,
but had not yet provided any information about PCIe 6.0 or CXL 3.0 availability.
Also, from technical support view point, I do not have any visibility on the new launch product before official news release.
If those information is really important to you, my best suggestion to you is to talk directly with any Intel Sales/Distributor.
Hope that will help you. Please accept my apology for that.
Let me know if you have any other further question.
Regards,
Wincent_Intel
