Don't expect RIM's fortunes to turn around any time soon. Only a catastrophic business failure is going to shake up the management structure. With RIM's financials and market position, it could be years before that event comes to pass. Even then, there's no guarantee that RIM would really make a recovery. Most likely RIM will be absorbed by a larger competitor (and the current RIM top brass removed) before anything like real business failure can occur.
It's so painful to watch this. RIM has really made some great products and services.
