I’ve never heard anything but rumor about Blackberry 10, but here is some speculation.
Blackberry 10 is based on QNX 6.6, and it runs using Screen. It is a closed system. That is, you can’t write your own resource manager or driver and put it on a Blackberry. User applications run in a sandbox and have limited and tightly controlled access to system functions. The fact that you are seeing an OS value of 8.0.0 suggests two possibilities.
- Blackberry 10 is intentionally a branch off of standard QNX 6.
- Blackberry 10 has new features that will eventually find their way into a general release called QNX 8.
Note that as a general rule, QNX has avoided odd numbered major versions. There has been a QNX 2, 4 and 6 so far.
For that matter, major release numbers involved complete rewrites so far. And to any of you old guys who think they know more than me, QNX 3 was not a release, just a system level indicator that QNX 2 was running in protected mode.
