If Kabuto is caught in IT while being blind then Sasuke's Susanoo would be pointless in protecting team 7... as Sasuke suggest it is LIGHT based so if you do not SEE the light then you will NOT be effected... and this is not Light to Skin based as some suggest because you would need to block ALL light which as Sasuke displayed is not the case
LMFAO he is Blind so IT's Light cannot effect him... he is blind as a counter measure for Tsukuyomi and Visual Genjutsu in general and Infinite Tsukuyomi literally means Infinite Eye of the Moon suggesting it to be Visual Based... so since Kabuto has an immunity to Visual Based genjutsu IT is ineffective.
Kabuto Cannot see but he has Super senses allowing him to perceive his surroundings instantly without having to see... He is using Karins ability(Shown in sasuke vs 5Kage) enhanced with Sage Mode... so he is blind but no where near defensless...
I have a feeling he is. As much as i'd love it they did show Orochimaru's band last chapter which gives the assumption they all got eaten up. Kabuto's protection against genjutsu might not be enough for genjutsu of this calibur.
Personally i'd LOVE Team 7, the Edo Hokage and Obito/Kabuto to be the final few. That would be an amazing fight and would make sense.
