yes but J-man and naruto are very much the same..
take a look at J-mans background..
he was kind of in love with tsunade who ignored him.
naruto was in love with sakura and she ignored him.
J-man had his own ''unique'' technique called: the peeping blabla whatsoever.
Naruto has: the harem no jutsu.
Naruto was bound to the pillar because he fell into all traps of kakashi.
J-man had the same with sandaime.
J-man was very loud and wanted all attention just like naruto.
So from taking a look at those points.
both of the personalities are kind of 100% the same..
maybe their goal and dream not and the looks..
and besides, that grandpa toad said that naruto will learn the hermits senjutsu..
besides J-man, naruto is proberly the second one who will get trained by them, thus making naruto having a very big chance on learning hermit mode aswell.
Look at Oro,Tsunade and J-man and take a look at Sasuke,Naruto and Sakura..
they are all the exact same typ and taking all 3 the same path
Naruto & J-man
Sasuke & Oro
Sakura & Tsunade.
and all 3 have learned their master's technique and followed the same path..
so i wouldn't be suprised if naruto will learn the hermit mode and most of J-man's attacks..except his hair techniques
does sasuke still have the curse seal? I thought at the end of the fight with Itachi the curse seal was taken from him.
after orochimaru got out of him the curse seal has disapeared..
itachi lured sasuke to use orochimaru so the curse seal would disappear, and he sealed orochimaru into some kind of dimension for eternity, thus oro can't come back that easily to try to get sasuke back.
Sasuke is cleansed from the snake, but did fel into the claws of the lion as a ''temporary'' prey.
ya sasuke doesn't have the curse seal anymore, that was one of itachi's goals. but he does have MS now which makes up for it. but he did lose orochimaru's powers too, since itachi sealed him away. sooooo...it comes down to losing curse mark and orochimarus power for MS.
sasuke did learned orochimaru's techniques so he proberly can still use some of them.
although he only lost orochimaru's powers and the seal, but not all techniques.
