You already have some idea of that; based on the public statements: http://nokiagadgets.com/2012/07/08/f...ced-this-year/ - though there's still a lot left unsaid there. Anything can happen.

Of course. That's the very definition of a startup: a high probability of failure. I do have a level of confidence in Jolla, though, through their seemingly fairly competent ways of doing the launch so far, and through their announced staffing of a bunch of ex-Nokia/ex-MeeGo people. I know that Nokia/MeeGo had a lot of talented people. Of course, they weren't exclusively great, but I have hopes that it's the good ones, and not the bad. :}

RIM bought QNX in 2010 (along with TAT for Cascades, and various other companies), and are currently working full steam ahead on producing BB10 out of all of these bits, more or less from scratch, so I don't think you've quite done your homework.

Just because they aren't using e.g. Android doesn't mean they're "emotionally attached", it means they want to remain independent. And that may not be such a bad idea in many respects, looking at how jumping into someone else's ecosystem is working out today with e.g. HTC announcing profit warnings, and Nokia's market share taking a continued nosedive...
