The show is called "Naruto", so I'd like to think not.
Yes of course he is more important than Naruto, i mean the show you watch is called Sasuke Shippuden right?
No,no,no...There's deeper meaning to the resurrections of the kages.Kishi is using the flashbacks to reveal more things about the past, which I can guarantee that will be important to the war, and related to other character besides Sasuke.so far it looks like sasuke's revenge is taking priority over the juubi

I'd think his importance is equivilant to that of Naruto's.
Their importance is equal. Without Naruto, Sasuke is not important or useful to the plot and vice versa.
