In the last chapter Sasuke showed his MS http://www.narutobase.net/manga/Naruto/592/2 he hasn't shown that form of eyes since he gain EMS, Some say its a error through Kish, i believe he still has unknown powers in those eyes before gaining EMS. After all, i'm one that believes that he doesn't posses Tsukuyomi.
In the same chapter he was presented with the scroll from Suigestu that would allow Team Hawk to rule the world. Then Sasuke says he must go see the Oricale to know if he is really 'The One' lol. Anyway, Sasuke needs to meet with Orochimaru. I believe Orochimaru knows more about the Uchiha and the Sharingan then Sasuke could in his entire life, so Sasuke power ups will start after his conversation with Orochimaru.
I believe those powers ups starts with his original MS to EMS to Rinnengan.
1. MS, he is still missing or haven't shown some type of power with his own MS.
2. EMS, is said to give a new power... Susanoo is not new, so its likely that EMS offers more then just the gate way to Rinnengan.
3. Rinnengan, this power up is a must. Sasuke need this just to compete with the top tier of the Manga,
If anyone one has more to add, feel fee to do so. Thanks.
unless he can become a "hawk sage" (which seems totally possible considering kabuto is a snake sage and naruto is a frog sage)
i think sasuke will be limited to the same powerups madara obtained except for the hashirama stuff (unless thats why hes going to see oro)
Maybe he'll get his curse seal back.
The thing I really would like for Sasuke would be an unique power/ability/whatever, just like Naruto's own is unique when compared to other ninjas, Jinchuuriki or not.
Instead he has the same Mangekyo Itachi has, only weaker, will probably have the things Madara already showed, like Perfect Susano'o or the Rin'negan, and so their final fight will be not Sasuke vs Naruto, but Generic Sharingan eyeball vs Naruto.
I would want Sasuke to obtain that Sharin'negan the Juubi showed, the supreme, most powerful eye power in the Narutoverse, even if it is only for their fight, even if Sasuke will lose his eyes or whatever, but just give him something personal, cool and uberfully haxed so he can really stand up to the big guys and overcame them, like Naruto did with the "good guys".
That, or give his EMS a powerful and unique ability that the "one that knows everything" or Orochimaru or whatever was in that scroll will give him.
No Rin'negan, Nagato showed us all its paths, and Madara showed how to incorporate it in an Uchiha way of fight.
If Sasuke's going to fight Madara or Naruto, the only powerup I can see him getting is Rinnegan. He can't really keep up with either of them without Rinnegan, and I'm not sure if Mokuton would give him an advantage.
Mokuton is the last power I think Sasuke would get. Just having knowledge from Orichimaru would be a good power up.
Kabuto mentioned that Orochimaru figured out the secrets of the Sharingan/rinnengan, so my thought is that Sasuke will get the Rinnengan, then faceoff Uchiha Madara with his own perfect Susanoo (eventually), leading to a Full Power Sasuke vs Full Power Naruto that will make 1st Hokage Vs Madara look like child's play.
This will probably be like 15 or 20 chapters down the line though, if we're lucky.
I don't see Sasuke getting any significant power-ups before the conclusion of the manga. Him getting the ability to use Mokuton would just be ridiculous. I don't see him attaining the Rinnegan. Perfect Susanoo is probably also out of his reach. Any power-ups are going to be advances in the techniques he already possesses, or previously unseen techniques. These could be original techniques he develops himself, or techniques he learns from Orochimaru or similar teachers. To be honest, I don't think it is necessary for Sasuke to attain power that is comparable in scope to the power that Naruto holds. It would be slightly ridiculous.
I have a feeling that Sasuke Perfect Susanoo is gonna be able to fly like a bird.

not out of his reach. And u right probably right, that any powerup would be avanced from the tech he already possesses and Susanoo is one of the tech Sasuke already possesses.
I hate the Rinnegan. I do. But it's pretty much a given Sasuke's gonna get it, so he should atleast get the eye that the First Uchiha had (the one that looks like a Rinnegan that swirls inward) http://naruto.wikia.com/wiki/Uchiha_Clan_Ancestor
I pretty much gave up on the whole "EMS grants a new power" hoopla that Madara and Itachi mentioned. No matter what it is it isn't comperable to dropping meteors or trapping your opponent inside their own mind for potentially eternity. I mean, if Naruto's supposed to be the pinnacle of physical energy and Senju (kinda) power... then Sasuke should be the avatar of spiritual energy and Uchiha power. He should literally be capable of anything his mind can come up with.
you do not know how many other descendants the guy had. byakugan is very probably another branch of descendants
it's like calling 'lucy' 'the first new yorker', or the ancient steel smelting techniques the chinese invented 'the first camry'. what about everyone else?
