We've started work on ROS 2.0, and are building it on top of DDS. A detailed announcement was posted to the ros-sig-ng-ros@ group: https://groups.google.com/forum/#!topic/ros-sig-ng-ros/fQLysM_AEFY More details and rationale can be found at: http://design.ros2.org/. Please give feedback, at that site and/or on the ros-sig-ng-ros@ list! brian.
