RIM's Blackberry Tablet might be seven inches, feature dual cameras and 1GHz CPU?

The rumor mill's been churning out quite the picture of RIM's Blackberry tablet over the past several months, and it's a research analyst who's most recently picked up the brush -- Ashok Kumar of Rodman & Renshaw, to be precise, who anticipates a 7-inch touchscreen device with a 1GHz processor, plus front- and back-facing cameras for video chat. Since that's a good 1.9 inches smaller than the slate rumored a couple months back, this latest spiel fills us with doubt... but hey, it's not like we had confirmation that RIM was even producing such a device, anyhow. It may be a while before we find out for sure, as Kumar told investors that even should the company succeed in an attempt to move up the schedule, the device still wouldn't launch until the end of the year.
