Turbine addressed in a new LotRO community Q&A forum post.
A majority of the questions had to do with upcoming content, in particular what's coming with Update 13. In addition to the revamp of North Downs, the devs are apparently working on retooling Misty Mountains and Trollshows, as well as adding "a small slice of new region content." A future Paths of the Dead update was teased as well: "You can expect to see the Paths of the Dead in some form. Aragorn's path through them is described rather specifically, but I think your character will have a different reason to enter and explore the Paths."
So what other features are the team working on right now? It sounds as though Rohan housing might be a possibility as are catapults in the Ettenmoors. Kinships and housing will receive some cross-feature love, crafters could see a wider range of tradeskills, and mail and inventory are both being worked on at the moment.
