I had a meeting with a RIM rep today who flew in from Waterloo and he gave me some info on the QNX phone that they're working on.
4.2" screen (wasn't sure, it might have been 4.3")
1280x720 HD screen
Dual Core 1.5ghz processor
Will attach to the BES via the Playbook administration service that should be launching at DevCon. So it WILL have native BES functionality.
Said that they're shooting for Q1 2012.
Take it for what it's worth.
