Sasuke was already in Tsukuyomi then.
Wrong. Itachi used Tsukuyomi after Sasuke killed the Karasu Bunshin Itachi created during their Shuriken-duel.
Insane hand seal is crap as Sakura, Naruto, Chiyo could avoid insane hand seal fireball from Itachi, SAsuke could match insand hand seal fireball of Itachi, Naruto and Bee saw Itachi form clone, nothing he did was 'too fast' for anybody in part 2.
I don't get your point. Well, there is no point in this statement. His speed of forming seals is insanely fast, I'm inclined to say instant - Gokakyu no Jutsu isn't. That's all. Since neither Kakashi's nor Sasuke's Sharingan were able keep up with his seals when he was doing them at full speed, his seals
are insane, and they
are too fast. He wasn't doing them at full speed when he fired Gokakyu no Jutsu at Sasuke, since it's a
changeless fact that Itachi's seals are faster than Sasuke's. At full speed his seals
are faster than any others we saw yet.
You really believe Itachi will prepare and fire Amaterasu or any technique before a Sannin with 4.5 in seals forms two seals for an instantaneous jutsu when a bird could fly out of Naruto's mouth to Itachi and back to Naruto before he could fire Amaterasu and blood dripped from SAsuke's face to the ground before he could use it against Raikage?
Why not? Close your eye, open it - done. Turson already provided enough pictures showing Amaterasu's immediate usage. You're just way too biased to get the fact that Amaterasu requires
no seals and can be used
without any preparation time. Even if not, what keeps Itachi from just jumping into the air? Nothing.
Any arguments supporting Jiraiya's victory are absoulutely baseless. Just face it.
