I've not a great deal in terms of a new season. However I read on the Sunrise official website for Code Geass and found an article posted yesterday here (http://www.sunrise-inc.co.jp/geas/news/index.html).

The rough translation reads: Broadcast at not yet televising area of Code Geass: Lelouch of the Rebellion, successively has been decided. Because it keeps renewing consecutively, please check abundantly.

Corrections are welcome. DC
