Namely, these teams are Mageia, which currently works on Mageia 3, and ROSA, which prepares the Rosa Desktop 2012 release.
Alpha 3 coming in November 2012, the ROSA Desktop 2012 release is already in Beta 2 stage.
Even though I am not that big fan of ROSA Desktop, and you can understand from my own review of it, I think this distribution still has a right to exist. I know it has some fans.
What is new in ROSA Desktop 2012? I believe there was a huge work for the "under the bonnet" stuff. But this is not so much visible to users. The interface changes are more likely to attract the attention. That’s why ROSA team created a short video where they explain the visual changes. Welcome to watch!
