I can't be disappointed about the various Sakura-related theories not coming true though. I feel like people were expecting way too much out of her, given that this arc involves everyone in the Naruto-verse, not just Team Seven, and not just Naruto and Sakura. It was literally impossible for her to be with the Kages, as she had no way to know that Tsunade needed help, nor a way to know her location, nor a way to get there quickly, nor a way to actually save her, nor a way to gain Tsunade's abilities and understand how to use them immediately and return to the battle in-time to fight with Naruto again. That's too much Sakura-focus in an arc that has no relation to her specifically.
As much as I liked the Kamui theory, expecting her to be the one to fight Tobi doesn't make sense either... Honestly, it's better this way. Kakashi is the one with the connection to Obito, not Sakura, so he should be the one to fight him. I'm really looking forward to it, actually!
This new theory about her stabilizing Naruto's chakra seems much more plausible than everything else we've been coming up with. At least it focuses on the abilities that she already possesses, rather than going off of the assumption that she's going to learn something new in such a small period of time with absolutely no opportunities to train. Plus, I think that will make for a really nice NaruSaku moment. Sakura assists Naruto in the final fight in her own way. It's not the size of what she does for him that counts. What's important is how she feels about him, and right now, she's worried about his health.
