A bump.
Anyways, I feel like we're nearing the next cover story soon. Judging by it, it should be stuff from Punk Hazard now. I doubt we can get any more from Fishman Island. Monet and Vergo are definitely going to be the characters of focus, considering from Punk Hazard. The only closest thing I could imagine is maybe following what Smoker is doing, though I doubt that (and I really don't want any more Smoker for a while).
Monet and Vergo are alive, no matter what the wiki endless argues over. By that, they either go through two routes: go on their own, meet some other characters along the way, and do some weird thing that may or may not affect the story (see Hachi's story and Gedatsu's story respectively); OR they regroup, see what happened to Dressrosa, and essentially go the Baroque Works route, with some differences here and there.
If you ask me, the latter is more possible, considering how dedicated Monet and Vergo are to Doflamingo. That being said, I don't know exactly how'd they reunite with the others. Maybe hijack the ship? Maybe there's another undercover deux ex marine? IDK. But they'd regroup somehow. Now what they would do afterwards is the question. I can see the non-elite officers separating and doing their own thing, like Miss Goldenweek and the others, while the remaining ones try to restart. With that, Doflamingo and his remaining men would probably serve the same purpose as the Thriller Bark crew is doing right now. They'd surely come back, but not for a while, probably causing some ruckus here and there (like Absalom).
Or maybe it'd be something entirely different, idk. But I doubt that Doflamingo is out of the picture. So far, most of the major villains of major arcs have a cover story, even if it's just a subordinate appearing somewhere (like Perona). Someway or another one of the Donquixote Pirates is gonna appear on a Cover Page.
This is actually getting me excited. The last cover story was kinda filler-ish, so hopefully this next one is gonna be cool. And not another Where Are They Now because we just had one.
Edit
It could also be Marijois and the Reverie. I very much doubt that though, but it's a possibility.
