Your comment reveals an ignorance about how Red Hat Enterprise Linux works. Different teams are working on different releases, mostly because the maintenance work on RHEL5 is very different from new integration work and development on the upcoming RHEL6 release.
That is why you can still run RHEL3 (which is almost 7 years old!), RHEL4 and RHEL5 and get security fixes for all three of them, while other people are preparing RHEL6. It's not an either-or thing, but rather an and-and proposition.
Of course, if you're only interested in the latest and greatest, you may not be the target audience an Enterprise Linux is looking for.
But that will change once you realize your computer exists to help you do work, rather than consume more time in spite of doing more work. And then the version or features or not that important anymore.
A computer should facilitate your life, not the other way around
