On a more serious note, they're going through a tough period, but I expect them to make it through. They are transitioning to a whole new OS, which is too new and rough (I played with a playbook a bit) to carry their product line, while their old OS is not good enough. The good news is that their strong performance until now gives them enough slack to make the transition.
By Holiday Season 2012, they should have both tablets and phones all transitioned to a polished version of QNX, which should allow them to be competitive. The smartphone market is also growing very rapidly, so if they manage to hold onto 2nd or 3rd place with ~15% share, that still means tens of millions, if not hundreds of millions of devices sold per year.
All depends on execution however.
