As what Omar/Evils told me, Lelouch will be alive because, if I remember [spoiler] his dad was immortal because he has geass on both his eyes, so if that's true then Lelouch would also be immortal because he had geass on both his eyes at the end too. But that is what he thought would happen. I personally would prefer the ending to be a cliffhanger just to tease everyone and continue the trend of guessing the ending. Which they did.
Please excuse me if i made a mistake in the story since this was told to me about half a year ago when I just finished watching the series too...
