I agree but they might not be able to afford to make something revolutionary.
I mean if they even want to ship any units at all right now they either need to pick Android or WP8. Now from rumour Microsoft are literally paying manufacturers (as opposed to Google who just give it away).
I think RIM are just trying to stay alive right now, they can consider their competitive edge later.
They're not going to stay alive if they don't introduce something revolutionary now.
Doing something revolutionary doesn't require tons of money, companies with far fewer resources than RIM introduce revolutionary products all the time. In fact I'd say most innovation comes from startups working on a shoestring budget.
