No, it comes out later as its own event, Return of the Dual Blade. Don't expect it til some time after summer. There was a small DB revamp with the rest of the thieves during this patch though, we lost the worthless owl, but got Channel Karma, Physical Training and Sudden Raid as well as had some skills changed between jobs.

In KMS, hilla was not part of the aswan update, she came with the db revamp.
It is already confirmed that TMS is getting aswan+hilla+db update as part 3 of their justice, and based on the teaser on the gms site, i can say that we're getting hilla as part 3 too, which implies db revamp.
