I'm totally be willing to bet money on this, though in that case I'd probably have to insist "end of the Doflamingo arc". Given that Ceaser is still an active character, and the entire previous arc was setup for this one, we may not get proper follow up till its done, ala Jaya. (But since Monet and Vergo were both defeated, its hard to see them being relevant again in this arc.. same for Baby 5.)
Four months ago it seemed the arc was going to end a little more cleanly. But the next cover story should still show the aftermath of Punk Hazard even if Ceaser himself is still in the midst of things.
