I think with Sakura being the healer, Obito's last request will be to take out the rinnegan and save it/give it to whomever, serving as a nice parallel to Rin and giving him the full closure of really dying this time around.
This!^
OMG, that would make me so happy! I know it's just a small thing, but something about that seems so...bittersweet. It would be a lovely ( and sad) call back to Rin. 
It could not only help move the plot along, ( and getting more Sakura time!
) but also, there is a good chance for a possible pairing talk! 
now, I know that some of you guys really, really, don't want that... But well, I'm sorry...I really think it would be a wasted moment if Rin was not brought up romantically, and Sakura and Naruto were not mentioned. It just seems wrong.
To me, like when I first saw that back story with Obito and Rin, I thought...somehow, Kishi is going to tie in this with Narusaku.
He just HAS to! 
I for one, have no problem with the way Sakura is protrayed... She is like a Heroine version of Keiko from Yu Yu Kakusho! 
( I would have loved her even more if they throw in some fight scenes! ) Which is one reason why I like Sakura so much, she is both the love interest, and a fighter! 
( and I just fangirled a little over her, sorry...I do that. 
Oh yeah! other things about this Chapter that I forgot to make note of...!....Let's see, I think that the dark panel really is a subtle clue that the "Holy Tree" is Kaguya. 
And she is up to something....something....EVIL! 
.......I'm excited!
