It’s not a good period for Research in Motion (RIM), with yet another setback upon it, this time a delay in the launch of BlackBerry PlayBook OS 2.0 until February next year.

“As much as we’d love to have it in your hands today, we’ve made the difficult decision to wait to launch BlackBerry PlayBook OS 2.0 until we are confident we have fully met the expectations of our developers, enterprise customers and end-users,” David J. Smith, the senior vice president for BlackBerry PlayBook, explained in a blog post.

The update has promised a number of new features, including integrated email, calendar and contact apps, a new video store, as well as new functionality that RIM has asserted will “allow one’s BlackBerry smartphone and BlackBerry PlayBook to work together even better.”

Additionally, the company added that PlayBook users will have to wait for a subsequent version of the OS for the popular BlackBerry Messenger (BBM) application to be integrated.

“We are committed to developing a seamless BBM solution that fully delivers on the powerful, push based messaging capabilities recognised today by BlackBerry users around the world and we’re still working on it,” Smith continued. He added that, in the meantime, BlackBerry smartphone users will be able to continue to use BlackBerry Bridge to securely access BBM on the PlayBook.

Apparently, investors were less than impressed with the announcement. According to Mashable.com, RIM’s stock fell 6% yesterday. Neither of these developments bode well for the company, which has been in need of something to bolster its image – and its tablet sales - after this month’s service outages. Adding insult to injury, Bloomberg recently reported that RIM was making little progress in the highly competitive tablet space, selling one PlayBook for every 46 iPads sold.

This comes at a time when companies are being encouraged to integrate employee’s personal tablet devices, running either Android or iOS, into their corporate networks, driven by the demands of employees and executives alike to use the tablet of their choice for work.  

In recent news, Research In Motion announced the next iteration of its mobile operating system (OS), dubbed BBX at BlackBerry DevCon Americas 2011.
