You might want to note that IF any RIM loyalists are waiting for BB10 then sales in this quarter have already tanked and earnings will be bad at best. Everyone else has already moved to iPhone and Samsung. Even US government agencies including US Marshall Services have approved use of and are already using iPhone and iPad. RIM is burning through cash and may not have any left by BB10 launch.
$ 1 billion saving in expense, fiscal year 2013, rim even with moderate sales of bb10 devices, going high. 4 billion service revenue v/s less than 3.5 billion operating expenses. Will see positive surprise on dec 20.
