I decided to read through the recent manga chapters and came up with a theory about knowing the names of the bijuu..(if it proves stupid let me know xD)
I think the so6p left bits of his chakra in each of the bijuus (just as naruto's parents did with him) after telling them they would be 1 whole again so that when they found the next host then he could meet the so6p, hence the reason the bijuus r fist bumping naruto maybe that is a way of sending through the so6p chakra to him and seeing as shukaku is the last 1 naruto is getting closer and closer to receiving chakra from all 9 beasts..this is why tobi is confused to what is different about naruto..i thought this only because when tobi was going through that speculation 1 of the images showed the chakra around naruto was similar to that of the so6ps...its just my theory but let me know what you think
