Fedora is good as it is now. It would be great if it was rolling release. Lot of components are already rolling. Moving to 9 months lazy schedule and having 20 months schedule is too much maintainence work and too little gain. people who use fedora use it for the cool new features. When a new release is made they switch over and just almost forget the F -1.
Rolling release will prevent the other major packages being held up.The current release model just holds off the new features when one of the un-related components is not ready.
Gnome 3.6 would have been available even at the end of september.
With the current release schedule Fedora is not bieng 'first' in recent times. Arch Linux beats Fedora all the time with software upgrades. The transition is smoother in Arch linux. Arch linux users do have the trouble of manual intervention once in a while, but that's ok, when you have the information put up on the main website about how to tackle it.
