They will get out of it, its a Shounen manga and it wouldn't make sense for the Infinite Tsukuyomi plan to fully succeed.
It just doesn't fit with this type of manga, we may get a brief glimpse of it but that is the most.
Also their isn't enough time to have a Infinite Tsukuyomi arc, the manga ends this year and Kishi has too many other issues to cover.
I don't know, it looked like the image on the moon wasn't completely shaded in, and Madara was still doing the jutsu seal, which might mean it isn't fully engaged yet...So there might be a chance that right before it engages someone stops him. Maybe someone like Minato, who has been conspicuously absent for the longest time...who knows, maybe before Minato got his arms blasted off, he landed a touch on Madara. How sick would it be if right before Madara is going to complete the activation of IT, Minato were to FTG and give him a good solid kick to that third eye of his lol
Lol that would be interesting, then madara rips both his legs off.
Its not going to happen like we expect it to. Technically if it is cast....the Manga should be over.... I think either Naruto and Sasuke will be immune or get something from Kishi.... I feel he is going for a traditional cliche ending. Or Sasuke has already cast it and Madara is in IT thinking that he is winning..... Which would be pretty awesome, but we would not ever hear the end of it from Sasuke fans. XD I think Kishi loves Sasuke more than any character...
