i remember kakashi telling shikaku that kurama's chakra made his kamui at least 3 times stronger and it enabled him to use it many times. using logic, that was only yang and presently sasuke has both the yin and yang.....and as chouji said, it's stronger than before. so do we get to see a x6 susanoo from sasuke or is he going to go on an amaterasu rampage? also i think juugo's senjutsu chakra will react quite well to d kyuubi's chakra......lastly, i do hope oro doesn't get any of dat chakra cause i see him somehow preserving or taking and storing some away 4 sasuke or himself like he did with hachib's.
The kubi chakra that naruto gave everyone, is just temporary,,,, when it is exhausted in everyone aka sasuke ,it would be finished,,,,,,,,, eg.....just like if u fill a car up with gas, when the gas is finished ,car shots down.
