According to a PCI SSC Blog post, the Request For Comment (RFC) phase has started for the newest version of the PCI DSS. The draft can be obtained at the PCI Portal (https://programs.pcissc.org/) which QSAs, Participating Organizations (PO) and ASVs have access. The RFC phase began yesterday and continues though December 13, 2019.
I tried to find the documents in the Portal, but I am guessing that only the Key Contacts for organizations have access.
Can confirm it was available for Primary Contact.
You are correct, only Key Contacts have access. This has been done to ensure all comments from an organisation are collated and in the format required.
The documents are only available to PCI SSC Participation Organizations (POs), Qualified Security Assessors (QSAs) and Approved Scanning Vendors (ASVs). It is said within the blog.
Even the Guru could not get them because I am not the Primary Contact for my QSAC. Only the primary contacts at each type of organization have access. That said, the NDA for these states that they cannot be shared our discussed outside of those approved participants.
