3 things point to a 3rd season, evidence as follows.

-Suzaku is told to always wear the mask of zero. Makes it easy for lelouch to switch places with him, given everybody thinks they are both dead. lelouch could kill suzaku or it could be a part of lelouch's plan.

-What he said to nannuly when he was dieing, "I'm the destroyer of worlds. I'm the creater of worlds". Lelouch obviously destroyed the world, but with nunnaly on the throne its obvious that he will only started creating the world. Lelouch isn't one to stand in the shadow of somebody else.

-Lelouch is still alive: At the end, the carrage drivers face is zoomed in on, but by the side. There is a paper swan by CC, which nunnaly taught lelouch to make. The music stopped and CC raised her voice, "right lelouch".

Not a 3rd novel to base season 3 on, but given the huge fan base it would be possible.

Code Geass Is The Best Anime I Like It
If got season 3 I can't wait to watch..
I Hope Got season 3 pls

Last Time suzaku kill lelouch so saddness
nunnlly can read past memory???
nunnlly touch hand lelouch and then nunnlly know the true..

OMG Code Geass was amazing. It kinda sucked that lulu died but it had to happen. Now suzaku is still alive and can't die because of geass. Guess thats his punishment huh.

the story of CG was totally unique...first time my friend told me that this anime was a good series but i just snub it because im too busy to my study but later on when sembreak comes after i watch this...i talked to him if their was a season 3...omg...
i hope there's a season 3...

Y'know... there are a few ways that lelouch could still be alive... but the one that bugs me the most is that he might have taken C.C.'s immortality... Well, in any case, as one of the biggest fans of this series... No, as one of the biggest fans of lelouch, I wanna see him alive again!!! So, like most of you, I hope that there's a season 3

first i love CG if you dont remember rewatch some episodes
Lelouch learned to make cranes from nanaly when she wished to make 1k of them.
Jerimah smiled when suzaku jumped to kill lelocuh even with order he wouldnt let someone kill his master.
CC talked to lelouch in car(only with his mother she could talk in mind becouse of her geass to have place in people hearts)
and most important VV passed Code to Emperor Emperor passed Code to Lelouch when he choke him. Code activates when person die first time.
Lelouch(RR got CR- Code Geass thats why name of series geass he got from CC so he could use it and code from emperor) and CC lived happily ever after for eternity
as for R3 i wouldnt like to see it they would have to destroy world for reason lelouch to reapear maybe schneizel to break geass like nanaly did but i wouldnt want it.

The story was definitely amazing. Although i'm still lost at some things but not much. I was thinking Lulu's body died like his mother. He lives in the world of C. And CC spoke to lulu at end telling us that he was still alive. I'm thinking ill watch r2 again to make sure i get the story.

I just plain hate Schneizel myself... So he would make a good villain if there is another season... But, then again... I wouldn't mind having anyone as the villain as long as there is a possibility of Lelouch surviving
