It seems like a premature announcement. No real roadmap as yet. Nokia reps are saying that Maemo 6 is MeeGo compatible, but I've no idea if I can upgrade my Nokia N900 to Maemo 6 either.
So now Nokia is supposed to maintain 3 different smartphone OSes (Symbian, Maemo and MeeGo) and brand all of them as "the best mobile OS ever"? Nice strategy to fight Apple, Google and MS indeed...
I wonder if this means they are dropping plans to move Maemo to QT? Moblin is Gnome/GTK based (as is Maemo currently) and Intel doesn't have Nokia's crossplatform reasons to be committed to QT.
