I think it's actually pretty pathetic that SVN support has just been added, when everybody is leaving it for either GIT or Mercurial.
I'm using GIT (I switched all my projects from SVN to git, thanks to Git-SVN last year) but I've heard very good things about Mercurial so I hope I'll have the opportunity to play with it soon :)
But Git (http://git-scm.com/) Integration would be nice to have as well.
Iam switching from SVN to Git now days and i can imagen that other people two are doing that.
