irrespective of what Zoro did in his own adventure, the arc has been moved forward without any significant effect on the main story.....
so, yeah...it is not "Zoro specific" arc.....but Zoro is major player in this arc....he will have a major role that will turn the situation potentially in the allies favor...he may becomes MVP of the arc just like Usopp in dressrosa or like Brook in WCI....but it doesn't mean that it is his arc.....Wano is not just land of samurai...it has pirates also....

I mean surely if Zoro got the Robin treatment of just periodically appearing in like two chapters and barely doing anything, the current story would not look the same.
