On the subject of Tobiroppo, I would wait to see the chapter before drawing conclusions about them. That part is curious.
I see three ways this could go.
1. They announce the defeat of the Tobi Roppo but we don't see their defeated bodies, if that ends up being the case then there is a good chance that they will come back.
2. We see their defeated bodies but Jinbe or someone else makes a weird comment about them, so if the second option ends up being true then there is a slight chance they might come back.
3. We see not only their defeated bodies but we also see something weird going on with them, which could maybe imply that they are about to get back up again.
If none of those ends up being the case, and we just simply see their defeated bodies and that's it then they are probably defeated for good.
