It’s no secret that the Playbook will be getting upgraded to the new BB10 OS. The question has always been a matter of timing. It was released yesterday from RIM via the wonderful world of tweeter that “Cascades support for PlayBook will come w/ the PlayBook OS upgrade to BB10, shortly after launch of 1st BB10 smartphone.” When is this you may ask? New BB10 devices are scheduled to be announced in August of this year, with a release of the first new BB10 devices in October. The upgrade to BB10 OS may still be a few months off, this could be taken as a sign of good news that things are moving along nicely and on schedule for RIM.
