an interview with Ten Ton Hammer, The Lord of the Rings Online executive producer Jeffrey Steefel spoke about future updates to the game, saying that the best is yet to come because now that Turbine has moved into Moria, the really interesting and fully-fleshed-out stuff from Tolkien's source material is only a few steps away.
Among those interesting things is the land of Rohan, which fans of the books and movies will remember is a kingdom that prides itself on breeding and grooming the finest horses in Middle-earth. Steefel went on to say: "When we get to Rohan, does horsemanship become important? Yeah! Us and our horses would be strung up if we got to Rohan someday and didn't pay attention to horses. And it's just a matter of when."
Mounts in LotRO have admittedly always been a bit basic (but in a good way!), so this could mean any number of things, but perhaps the most exciting possibility would be Age of Conan-esque mounted combat. Go ahead and meditate on that for a bit, and read the interview for a few more vague quotes about the future of LotRO and the company's console plans if you feel compelled.
