For RIM to have any chance at being the market leader once again they must do what the iPhone did to the mobile industry back when it was first introduced. Anything under that just means a slower death.
What could it be? I believe making a phone itself is useless at this point. Why not look in to Pranav Mistry's SixthSense? Something of this caliber is what is needed to make the 'next big thing'. Competing in Apple/Google playing field is futile, a new field is needed.
Although I had high hopes for RIM (ex bb user), I highly doubt their execs are even in this mindset^^^.
