Weekly shipments features Old Republic characters which may mean that Jedi Revan will be back within the next week or two.

With the new Legendary, Han's Millennium Falcon most likely coming on January 17th and JTR the following week, it's hard to see Revan coming before the end of the month at the earliest. February is most likely Sith/Dark Side which means Revan may not be back till March at the earliest. I would plan to keep farming for Revan as soon as you can, just in case.
