It seems an update to the Motorola Z8 may be on the horizon. O2, a UK operator, has the Z10 listed in its coming soon section. The picture (see full story) shows the bottom half of a phone that bears a striking resemblance to the Motorola Z8 which runs UIQ 3.1 on Symbian OS. The specifications listed include a 3.2 megapixel camera (up from 2 on the Z8), 3G and 30 frame per second video. 

The usual caveats about leaks apply - there are no guarantees as to the accuracy of the information and changes may occur. 

Thanks to MotoSmartphones for the tip off.
