Microsoft confirmed they'll release a new version of Windows Mobile before the launch of WM7. This new mobile OS will be named Windows Mobile 6.5 and it may arrive as soon as Q1 2009.
Following the announced delay of Windows Mobile 7, an intermediary upgrade step has been confirmed. While visiting Australia for Liberation Day, Microsoft CEO Steve Ballmer spoke of the Windows Mobile 6.5 upgrade for next year in his roadmap.
In talking about Windows Mobile 6.5, Steve Ballmer did not go in to specifics but did hint at an improvement in the interface and flow of the software. It is believed, however, that this will be the first release to contain the reported Zune software integration instead of the much delayed Windows Mobile 7 release.
Windows Mobile 7 is believed to be scheduled for Q3 2010.
