Through this community Q&A, we learned that the team is working on a way to disable experience gain, has put additional hobbies on hold, has discussed and mostly dismissed multi-attachment mail, and is considering how dynamic events might work in the game.
So do the devs play the game they make? Sapience says they do: "I think you'd be surprised at how many people at Turbine play LotRO on a regular basis." There are also a lot of interesting tidbits in this Q&A regarding the decisions behind prioritizing features, expanding into certain regions, and how the teams work in tandem to produce content.
Finally, Sapience said that players should be seeing pre-order information for Riders of Rohan "Incredisoon™" and that there will probably be ways to attain the game's soundtrack in the future.
