This is all the info but there is no specific date

As of right now, the only information is that it is comng out in 2012, and i'd say to not lose sleep over it, as it might no ever come, since many things on carton network don't live as long as that did, and some shows promised a final season but never got it. plus it might not be on cartoon network, as some minor cannels 表示する this cartoon/anime. all in all, i'd say e won't get much もっと見る on a release 日付 until we get closer to what it is.
Ex: if it comes out in March, Cartoon network might 表示する a プレビュー febuary.

We don't know exactly when Code Lyoko Evolution will come out yet. It is going into production in early 2012, so we think it will be out late 2012.
