The number of original trilogy characters making an appearance are being kept to a minimum, and the fact that the rumored Boba Fett spinoff movie has never been confirmed makes it less likely that Lucasfilm knows what the future holds for the character.
There was another rumor that seemed to imply he’d be appearing here, however, and that one’s next.
While we don’t have any reason to completely discount this rumor, it would seem unlikely.
We haven’t heard or seen anything about anything Boba Fett-related since then.
