And from what I've heard about the new Code Geass, it's not going to be an extension of the previous one, but it will have all new characters, a new place, and a new plot. I think there was something about a surprise appearance by a previous character though. We'll see.
There is a manga that is supposedly like a 3 season but it's just like you said, different main char, different plot, it's in a whole nother time zone. Though there is the appearance of Lelouch and C.C though that's about it but because the story and the time zone are completely different it just wasn't as interesting to read.
