Joy to all!!! Sonic X will most likely begin the 2nd season starting in France (dunno why) on Jetix starting with 2 new episodes on March 12, 2005 at 18:05 French time. The rest of us should get it next fall. You can see the details, some screenshots, and a 45 second trailer on the site below. This looks promising!
