"The CentOS Project will expand its mission to provide additional open source technology-specific variant editions of the core operating system. Such editions will be capable of serving as a foundation for multiple, complementary cloud/virtualization projects. A current example is the Xen4CentOS project, which provides the components required to use CentOS 6 as a Xen host. Future examples will likely include variants to provide the virtualization component needs for OpenStack and oVirt, and variants providing hardware support and component updates for web hosters."
So they're publicly committing to continue to support that.
