As others have mentioned already in this thread, the git-svn bridge works very well. You can adopt git and get a bunch of its features (local repository mirrors and multiple local branches) while still working atop your SVN repository. You give up some things (you can't really do cross-repository merges with git-svn -- when you want to communicate with your peers you have to do it via the SVN repo) but it is still great. It's not worth waiting another five years for the extra features. ;)

I've found that the CVS-to-git workflow is a bit more annoying. You can import CVS repos into git, but you can't really push anything back without using patches.
