I'd expect that the layoffs would be centered around the old OS. Anyone involved in the new OS is likely to be safe. Or at least that sounds like a logical approach.

I'd expect the layoffs to be around 5% maybe at most 10%, but really things can still turn around for RIM if they can get their new OS out in mass, so I think we are still not quite in a complete panic.

Hopefully they start by eliminating their redundancy of having 2 CEOs. I know that'd be my first reaction if I was a RIM engineer.
