Code Geass R3??? D: opinions, ideas.?

Ok I'm pretty certain that there won't be a third season because it would ruin the awesome-ness of the show. BUT if there is any prof that there still will be a r3, then I would really like to here it. And also everyones opinions about the topic. And I'm also kinda confused about the whole thing about whether or not lulush had died. I mean I dont think he did, he had become immortal after he killed his father....right? So him and c2 will live together forever.
