Maybe this is The Wrap looking to get out ahead of everyone else. Disney did not confirm or comment to their claim. A Boba Fett origin story has long been rumored as a possibility. Someone in The Wrap's camp has enough to go on now to claim it to be true.
With this report it looks more and more that every Anthology film will be continue to be free of Jedi. The first film, directed by Godzilla's Gareth Edwards, will be a Dirty Dozen style flick about the stealing of the Death Star plans.
This second film will focus on the famed Mandalorian warrior turned bounty hunter with less screen time than a Gamorrean guard at Jabba's palace. It is very likely that it will explore the untapped world of bounty hunters in the Star Wars galaxy.
It will likely be some time before anyone commits to what the third Anthology film will be about, since we should not expect that until 2020. We have time.
