Expect the scrip system and collectibles to continue through the end of 3.x. Everything added for crafters in HW has used them.

Favors, on the other hand, haven't seen any updates at all since 2 weeks in to HW, apart from a couple nerfs and the Azys Lla fix. I hope they decide to use another means for materials in 3.3, but favors are still possible.
