Yeah i know this thread should be outdated but by re-reading some mangapages, i found this one and i still find it hard to believe it's Obito who was talking here

Like really? :sy: Kishi changed Tobi's identity at the last minute. I'm sure of it xd
Idk, I too didn't want to believe that Tobi was Obito at first either, but looking back at some of the highlights, alluding hints were given. Starting with the Kakashi gaiden, which set the stage for everything, particularly the current war-arc. Then there was the Tobi and Konan fight, it showed a overly wrinkled face yet the guy didn't seem old; and again when Tobi almost revealed his face to Sasuke but the black flames jutsu auto-activated from Itachi's set condition. Lets also not forget that during the Minato vs masked-man fight, after he was rasengan by minato, the masked-man's right arm started to melt. We later learn that Obito was wearing a body suit from Obito's flashbacks, accounting for the height/age difference (which was the bases of my disbelief on the tobi-obito theory; the time-age lapse), and his 'full' self. Also, someone else brought it up, when Tobi first encountered the Konoha X, how Tobi kept subtly directing some comments to Kakashi. Then there's the connection with Kakashi's sharingan and the other sharingan with the masked-man/tobi.
As far as what Tobi said/done up to his revelation it can be assumed that he was playing a role--a ninja actor--sort to speak. In other words, whatever Tobi said/done in the past can be seen as a cover to keep his identity a secret. After all, he did convince countless people that he was Madara, then Tobi.
What's left then is the discrepancy at Kakashi's death (and later resurrection) during the pain-arc, and how he 'saw' rin-minato-obito in the after life. I recently re-saw Naruto Shippuden episode 159: Kakashi vs Pain. I'm convince now that he never actually saw them but rather used their memories as a way of accepting/entering the after-life realm. Similar in principle to the 'light as the end of the tunnel' phenomenon some people have during near death experiences in RL (real life). So once Kakashi passed through that "bridge" of life and death the only person he actually saw and communicated in the after-life was his father.
When I first read the manga and later saw the anime, I too believed that Kakashi saw rin-minato-obito in the afterlife. Never once accounting the possibility of Kakashi going through in-between life and death stage, or that the anime and manga would actually SHOW that he was going through it. It was an oversight on my part. Anyways, just saying my 2 cents. No hard feelings.
