Earlier today, a listing for Destiny 2's first expansion went up on Microsoft's store. The expansion is called Curse Of Osiris and centers on the Warlock Ikora:
Destiny 2 Expansion I: Curse of Osiris continues your Guardian’s journey with all-new story missions and adventures set in a new destination, Mercury. Journey through time and space to learn the secrets of Osiris, avert a dark future, and rebuild the ties between the legendary Warlock and his greatest student – Ikora Rey.
We reached out to Activision to confirm that this is an official listing and the publisher has verified that this is the case.

As someone who hated the first Destiny, I'm actually really enjoying my time with the sequel so I'll probably be checking this out when it rolls around.
