I don't think MeeGo (or Harmattan for that matter) will completely die within Nokia. Seeing that we still get updates (PR1.3 is somewhat confirmed) and I think it won't exactly stop there. I presume at least one special person within Nokia will keep it running somehow and that is Marko Ahtisaari himself. If you look at his Twitter timeline you can see that in the recent weeks many of his tweets still came from his N9 and I don't think it only was to try out PR1.2. I think he is the one who keeps the Harmattan efforts alive as he is important enough for Nokia to not shut down his personal baby.
