RIM has over 1B cash, has about 16,500 (soon 11,500) employees. Most of their loss was from writedowns, so their burn rate might not be too bad. They might have time to switch to Android. They can't afford BB10 to flop, but I'm pretty sure it will (even if it's actually a great OS).
If they can loose some heads, and switch to Android, they might generate some confidence which could help them get funding. An Android phone with a competitive advantage (in some niches) over Samsung is something I'd bet on. A phone with a new OS in 2013 is not.
