Well blackbberry you were a tech company who refuse to innovate really I only see on of two possibilities become a android OEM or fail and get Google, Apple, or some other company to buy your name and patents. It's sad because they had plenty of time, but scoffed at ever lose the smartphone wars with such a significant lead.
I don't see how becoming an Android OEM can't be a win-win situation. Blackberry keep their brand and don't have an OS to maintain (maybe just a handful of Blackberry Android applications instead).
