The never-ending series of leaks regarding RIM's BlackBerry London continues, with a new tech spec sheet supposedly giving us a detailed look at what'll be powering the high-end forthcoming BB10-powered smartphone.

RIM is said to have three L-series BB10 models planned for 2013, the London, Lisbon, and Laguna. The London's the most interesting for us lot, as that one appears to be the GSM unit designed for sale in regions like the UK where 4G is still a distant dream.

The spec sheet claims the BB10 London has a 4.2" display running at 1280x768 resolution, with an 8-Megapixel camera, microSD card support, something RIM is calling "Face Detect" and your usual Wi-Fi, Bluetooth and DLNA connectivity options. It'll be powered by a Texas Instruments OMAP4 processor, which is all well and good, but in a phone launching in 2013 that might struggle to impress those after a properly cutting-edge piece of hardware.

There's bad news for those hoping for some 4G action on the next BlackBerry too, as the BB London currently lacks LTE compatibility. If the leaks are to be in any way believed, of course. [Rapid Berry]
