i dont think you can breed hinata and sasuke to get a new form of eye jutsu. i think the kids will have either byakugan or sharingan. much like if you breed a white rat and a black one, the kids wont turn out grey. it will take generations for the byakugan and sharingan to merge into a new bloodline limit.

@greateachermin: you dont need to use spoiler tags in the manga forum.
