The Resurrection of Lelouch was confirmed on November 27 at a Code Geass 10th anniversary event, along with 3 films that will do a recap of the anime. The format of the anime or movie is not yet confirmed.
It is worth remembering that the adaptation of the Code Geass manga removed practically all the mecha, for those who don't like it, maybe the 3 films that will recap the anime don't have so much mecha. The continuation of the anime will take place a few years after Zero Requiem and with Lelouch of course xD. Now it's time to wait for more details about this 2017 adaptation, in the future I'll update this article.
