According to those who enjoy keeping track of RIM's performances, the BlackBerry maker is preparing to reveal its first BB10 device in the summer, with a launch of the new hardware and software combo set for this autumn.

The news comes via site N4BB, which claims its "source" says the first BB10 device will be an entirely touch-based piece of hardware, which will go on sale by October. Those for whom BlackBerry is NOTHING without its usual QWERTY keyboard will be left waiting until early 2013, when RIM is expected to release its first BB10 with a physical keyboard.
