Rumors of RIM working on a wireless keyboard case for the BlackBerry PlayBook are alas coming true. Folks at the BerryReview have caught hold of a few slides showcasing the keyboard and are also reporting that it should be available in the coming weeks. We believe that its launch is most likely to coincide with the BlackBerry PlayBook OS 2.0 launch. According to the specs mentioned in the slides, the BlackBerry Mini keyboard will let you control the Playbook and will feature a touchpad and a keyboard for that easy typing on-the-go. Once charged completely, the keyboard’s battery will last up to 30 days (approximately) and will come with a leather casing which will tightly tuck-in the PlayBook. We’ll update you guys whenever we hear about its official launch.
