RIM plans to its PlayBook, smartphones and even embedded systems under BBX, a single operating system based on the QNX OS, co-CEO Mike Lazaridis told a packed keynote session at the conference on Tuesday. Though the company gave no details about future QNX-based phones or a new version of the tablet, nor a commercial release date for an updated PlayBook OS that it introduced as a beta, attendees were happy to see a firm technology plan.

The BBX OS will be the foundation of the company's software platforms for the future, along with BlackBerry Cloud Services. Developers will be able to choose RIM's native SDK and open-source tools, or the HTML5 Web standard and RIM's WebWorks, to build apps on top of that foundation.

Lukewarm sales and lowered prices have been reported for the tablet, along with speculation that the product would be discontinued in the face of competition from Android tablets and Apple's iPad. But RIM stood by the PlayBook on Tuesday, even giving one out to every attendee.

"We're absolutely committed to the BlackBerry PlayBook. There's no doubt about it," Lazaridis said.

The news will set casual-games company Concrete Software on a path toward developing games for the PlayBook, looking to have those same games run on future BlackBerry smartphones, said Keith Pichelman, the company's CEO. Concrete has been selling games for BlackBerry phones since 2004 and offers them for the other major mobile OSes as well. It had held off on creating for the tablet.
