According to multiple sources, RIM is planning on releasing its sequel to the BlackBerry PlayBook around the holidays. The screen size is the main difference. The PlayBook 2 would likely be an additional PlayBook model as opposed to a second-generation tablet.
And it looks like this tablet will be in the 10-inch size. The current model has a 7-inch screen. The first model is selling well if you believe some analysts, so a larger version with an updated OS that includes an email client, BBM and more could be a home run. Makes sense. Hopefully we will hear more on this soon.
