I'm assuming somebody else will pick up QNX, or it will be split off into it's own company. I don't think most people realise the value of QNX, maybe not as a phone OS, but in running so many other devices.
Interestingly, RIM doesn't say how much revenue QNX makes for the company. http://tech.fortune.cnn.com/2013/04/05/the-little-known-comp...
