Since it will be launched as a Marvel NOW! title, Superior Spider-Man
#1 should indeed serve as a "jumping on point." That was one of the purposes behind the Marvel NOW! initiative, after all.
Until any of us actually has SSM #1 in our hands and has read it, I don't think we can judge whether or not it will in fact serve as such, or if it will be incomprehensible without having read at least "Dying Wish."
