Well, at least, that’s the opinions held between Goro Taniguchi and producer Yoshitaka Kawaguchi of a musical of the series.
No official word of what type of media (TV, OVA, Motion Picture) the new Geass project will take yet, however a announcement will be made very soon.
For now there is the upcoming Code Geass: Shikkoku no Renya.
On the Gundam 00 front, the February issue of Newtype magazine should be dropping some major information about the movie.

By my guestimate, it’s probably premiering in Japan between late February (After SE III, which premieres 2/23), and Golden Week.
