They'll probably jump ahead a couple years and the story will start with Leia having died after the events of Episode 8, before Episode 9 begins.

Spoiler:

Honestly, they should've just let her die in the attack on the bridge. They could've further complicated Ben's internal struggle by giving him this chance for redemption, but he's driven further towards the dark side by her death at the hands of the First Order.
