Well if he does, it will be limited and wont be much use since his current attacks are mountains busting ones. There is a possibility that he does have senjutsu, but that would kinda ruin the show's theme. Naruto is the body of the juubi/Rikudo while sasuke the is eyes of the juubi/rikudo, why would sasuke get Sage mode or senjutsu? It's like Naruto getting a doujutsu, it's just not right.
It's possible he will get senjutsu, but i wouldn't count on it too much. I want sasuke to use his rinnegan eye more, rather than senjutsu.
