SharePoint 2013 compatible w/ AX 2012 R2?

Hello,

When attempting to deploy Enterprise Portal on AX 2012 R2 RTM, I am getting a prerequisite error "To install Enterprise Portal updates to SharePoint 2013 are required. These updates will be released by the SharePoint Team when SharePoint 2013 becomes generally available (GA)."

It doesn't provide any specifics about which update it needs and I can't seem to locate the appropriate one.

Thanks in Advance!
