With Dory and Brogy here to back up the strawhats it's 100% guarantee the next arc will be elbaf
So I here's what I believe will happen
1. I don't think it will be a major action filled arc I think it will be more of a Zou type arc mostly plot progression and lore building so 60 chapters or less
2. Saul reuniting with Robin will be a major plot point of this Arc, and he may be revealed to be the man with the burned scar
3. One of the giants will have a message to luffy from Shanks idk what the message will say but I believe he may leave one
4. Loki reveal- We'll finally see Loki and he'll either be a noble leader and the strongest giant by far or he'll be another Orochi type perverse and actually really weak
5. Usopp challenges a giant to a duel and pulls out a win akin to the David vs Goliath story showing how brains can over come brawn
6. A Major event that sets up the next arc
I believe that is what may happen during the elbaf arc
