I can't speak for WP8 but Blackberry still has customers who although have switched to Android/iPhone, loved their blackberries. And there is a case of, many corporates still using Blackberries. The land has been sliding but if RIM can win those users back, there is hope. Now I see the ecosystem problem,but for RIM (or anyone willing to enter Mobile OS market), it is a chicken and egg problem. They can't move onto next step, unless they have a strong phone. So nobody knows if BB10 is going to work, but at the moment, it seems like a good idea.
