According to an article over on gsmarena, HTC have been busying themselves with the HTC Leo which will probably be known as the HTC Pro 3 which runs on a 1GHz Snapdragon processor.
The HTC Leo also sports a 4.3 inch WVGA touch screen with Windows Mobile 6.5 and TouchFLO 3D on top, and has 320MB of RAM and 512MB ROM and the specifications of the HTC Leo have already been well documented.
The HTC Leo was snapped in comparison with the HTC Touch HD recently and looks to be somewhat thinner, but also larger due to its large touch screen.
