No, Fuerte was 1.8, Groovy is 1.9 (Changed the even-odd cycle), Hydro 
should be 1.10 (not 2.0).
See http://code.ros.org/lurker/attach/3@20130104.210053.794d21eb.attach
Feel free to update the wiki.

I believe the only "official" communication about ROS2.0 was by Ken when 
he handed over work:
http://comments.gmane.org/gmane.science.robotics.ros.user/16100
I have not seen other official communications of plans or roadmaps so far.
