Will BlackBerry OS 10 Even Make a Difference for RIM?

RIM CEO Thorsten Heins is either in denial, or really knows something no one else does, because he is adamant that RIM is not completely screwed. With stocks tumbling, market share declining, and BB OS 10 delayed until 2013, it will take nothing short of a herculean effort to pull the hardware maker out of its nosedive. But is the promise of an improved OS alone enough to save RIM. Do you think it's too late at this point?
