Sunrise Indicates Possibility of More Code Geass
Quote from the creator of Code Geass:
"All of you have shown us much appreciation and made the DVDs as well as the CDs so popular. Really, we have been blessed with fervent fans. Thank you very much. Like we have said before, [a major character development happened] but Geass cannot die. It just ended, but we think it would be nice if we can still do something more. In any case, when we can announce something, in the not-so-distant future"
