User blog comment:Jojo-a-gogo/Do you guys think that the 2011 anime will continue to use "Departure" as an opening theme throughout the whole series?/@comment-2169497-20121007204633

From the looks of it there might be a new opening once the greed island arc starts. As you can see the departure opening doesn't have any greed island footage and is only updated with the phantom troupe showing their nen powers. Therefore, it looks to me like this opening won't last another 26 episodes and just until the end of the arc.
