Wild ride......no doubt.  The only reason SP is at the $13.50ish level is BB10..... the cash burn rate will be interesting and any hint of delay will push SP below $10 again, very quickly....
I'm wouldn't touch RIM with your money let alone my money. 

If I were a gambling man I would play RIM short but only with small amount going forward, assuming they have less then stellar quarterly.  RIM has the potential to easily move beyond $15 very quickly.....

For now, best to wait for quarterly tonight and evaluate tomorrow or wait until 2013.....

SP could go either way, no way to chart the move, unchartered waters.....
