Is BlackBerry Planning a 10-Inch PlayBook Tablet?

The Playbook's 7-inch stature didn't bother our reviewer Matt so much, but people are whispering that RIM is preparing a larger 10-inch size, to go head-to-head with the iPad/Motorola Xoom. BGR is hearing it'll be later this year, and that the newly-announced BlackBerry Bold 9900/9930 handset's "summer" launch is expected to be August at the earliest. [BGR]
