i think this should be in the manga section because it reveals a bit from the manga...

that guy is not deidara in any shape or form, if you look back, it shows you exactly who every one of the pein clones were, and the guy your saying looks like deidara, looked exactly like a guy from jiraiya's past with some facial piercings, so all in all, that is not deidara.

also we arnt even sure who the real pain is, thats just the body he uses to represents himself, Jiriaya makes it sound as the real pain is none of those clones.

but there is no reason to think there isnt any upgrades to byakugan and rinnegan, i mena we have had i think four upgrades for sharingan. but i think its a bit early to be thinking about this, because we really, have no clue what exactly rinnegan actually does.
