True enough, Gundam 00 ("double-o")'s character design is by Kouga Yun (Gunota)...
This particular Gundam series is apparently a return to neither the U.C. nor the C.E. universe - i.e. none of the SEED characters will appear (although there is meant to be a SEED movie currently in production, with all the relevant characters returning).
p.s. I'm annoyed...can't use Firefox to get onto the Japanese website, and IE hasn't been working for me at all...
