Here’s a Windows Mobile 7 Roadmap with dates pertaining to Windows Mobile RTT (released to testers) - not device to market dates. This roadmap comes from a Windows Mobile 6.5 presentation given a week and a half ago. Another point of mention is the picture inclusion of a phone using the Organic User Interface we've seen in some of those conceptual Microsoft videos.
Also, a humongous version of the mock-up UI phone:
Lewis Shepherd of Microsoft had a presentation titled "Defense 2.0: Transforming DoD Through the New Paradigm of IT" at the U.S. Department of Defense (U.S. DoD). There are two slides of interest, in the first, notice how some of the text blends in with the larger white cloud clip art such that you can't read it?
Though the slide is fairly self-explanatory, the finer details of the clouds present on either side of the DMZ are of particular interest: MashupOS. What is MashupOS?
