Neji fell face first, so we don't know if the seal disappeared.

I don't think they'll kill off Neji before letting him have a proper fight with Rock Lee, with his new view on life. You know, instead of "You can't beat me because of destiny" it's "You can't beat me because I'm better than you."

But yeah, until Neji and Lee have a proper fight Neji's probably going to live.

Chouji I'm not so sure, but I'd like to see what Ino thinks of thin Chouji.
