After weeks of testing, CentOS 7 has been released. For a list of RELEASE NOTES, please see the Wiki.
CentOS falls in line with Red Hat Enterprise Linux 7, released just 26 days ago. It is also worth noting that an ALPHA release of Scientific Linux 7.0 is also available for testing.

But, unless I miss my guess, all the old file systems are also supported, and you can choose one or several at install time. (At least its that way with Opensuse, which I tend to use more often than any Redhat derivative.)
So people upgrading stick with what they have. People experimenting choose the new. Everybody happy.
No, you are mistaken. I've always had this sig.
