I think this song is about Slipknot's evolution musically - shedding their "bitter skins again" about how they change musical style with each album, and hiding "little sins again" by covering the hidden hateful meanings throughout their older songs with a new style. "But now it's over" meaning they have abandoned that branch of their roots and are now looking forwards to a more 3-dimensional way of getting their messages across. It's a kickass opening, fitting for such an almost flawless album!
