Just for the sake of irony, I think he is, or at least an evil clone or twin or something.
Oh goodness, you've got me started. {Warning: lots of spoilers ahead.}
What makes me think, is that jutsu that Orochimaru used against The Third in their battle at the Chuunin Finals Arena. It seems to show some type of foreshadowing when Sarutobi managed to stop the third coffin from rising up, which, if following sequence, would have held the Fourth Hokage.
Personally, I would suspect that even if the third coffin would have successfully opened up, there would either be just a corpse there... or nothing at all. The evidence for this comes from the very fact that the Fourth sacrificed his life/soul to the jutsu to seal the Kyuubi. Therefore, there shouldn't be a soul to summon to the sacrifice that was used to summon the coffins in the first place. Another theory might be that the Fourth survived in some strange out-of-the-box way and that the soul is still inside the body.
Further more, the only reason why everyone thinks that the Akatsuki Leader might be the Fourth Hokage is because he demonstrated a weird technique that transforms him into a spinning yellow ball and pummels everything in its wake.
And that's it... Heheh... okay, I'll stop. sweatdrop I think the same way.I think the third coffin would only have a corpse, or a body. Not the soul of the person. Yondaime's soul still lives on in Naruto IMO, not dead like the past two Hokages. I believe what that jutsu does is bring back both the appearance of the person and the soul of the person back to the living under the summoners control, but if there was no soul, it would just be a dead body.
I think maybe its like the body of the Yondaime thats the Akatsuki villan who can use all his jutsus, but the soul is inhabited by another user.
I also think the hair and chin look the same >_<
