I think that Hestia and Pandora's jar will appear. Since Gaea is supposed to rise on August 1st, the day of Spes, who is the Roman counterpart to Elpis the embodiment of hope, it seems like RR is setting up for the box to reappear. And since Hestia is the guardian of the box, I'm guessing she'll reappear too. She has to appear in the last book, she's the last Olympian.
