There isn't a single doubt in my mind. Vivi will reunite with the straw hats in the next 10 to 15 chapters, but there's a twist!
Now that the crew has been split up, I believe Vivi will meet up with Robin's group which will enable them to get acquainted with her since none of them ever traveled alongside her. (It's no coincidence that Chopper is a part of Luffy's group when he isn't even an OG) We could get really interesting character dynamics between Vivi and the other strawhats, especially Robin. Oda has a unique opportunity to write some dramatic tension between Robin and Vivi and hopefully forge a very strong bond between the two as the arc progresses.
The arc hasn't even started and we already have boundless opportunities for a strawhats centric plot where they reforge their bonds with each other and reach their ultimate form as the crew of the future pirate king.
P.S: it also helps that Vivi already knows both Dorry and Brogy.
