Re: Fedora updates
Clementine 1.0.1-2 is already in the Fedora repos for F16
VLC and Nvidia aren't in the Fedora repos at all, and you would have to ask the people over at rpmfusion that question.
My guess on VLC would be that it depends upon how many dependencies are changed from the 1.1.xx version. If there is much change in the dependencies, then it probably won't get into F16.
