As posted on the official LotRO forums, Facebook, and as an official news article:
It's been a few weeks since we announced ourselves as Standing Stone Games, and we are now excited to share our plans for the year ahead with you.
Firstly, we want to thank everyone for their continued support as we write some of LOTRO's most exciting history. This is the year that LOTRO ventures forth into Mordor! We currently expect to release the Mordor expansion in the summer, and we'll have a lot more information as we get closer to the day of its arrival.
Prior to Mordor, we have two big things happening in Middle-earth: Update 20, and our 10th Anniversary! We can't wait to celebrate a decade of Lord of the Rings Online with you. We'll be bringing out a new event that will serve as a fun centerpiece to complement the festival, along with our other, usual fanfare. We are planning a lengthy celebration livestream on Twitch and YouTube to celebrate a decade of LOTRO. We will see you in livestream chat and in-game!
Update 20 will feature the region called the Wastes, where players will adventure through the bleak Noman-lands, dismal Dagorlad, and up to the very Slag-hills of Mordor. We will also take players to the Battle at the Black Gate, Lord Aragorn’s last, desperate gambit to divert the Enemy from the real threat. Delve beneath the earth through winding maggot-holes and the Towers of the Teeth in two capstone resource dungeons that can be played in solo and fellowship modes. Finally, Update 20 will offer you a chance to help the various companies within the Host of the West prepare for their final confrontation with the Dark Lord. In addition, the update will feature a new Featured Instance rotation, among other things.
With Update 21, we shatter the Black Gates and march into Mordor for our first expansion in nearly four years! In it, we will cover the fate of the One Ring and then embark on new epic tales, foraying into multiple regions of Mordor after the fall. There, we will encounter strange new monsters, new mechanics, and new treasures to be won. We will begin whole new storylines that look deep into Mordor and hint at things yet to come. We are making plans to debut a new playable race, the High Elf, along with aesthetic improvements to all playable races across the board. We also plan to add large group challenge content in the ensuing update.
Update 22 will round out the year, and is far enough away that we'd like to keep its content under wraps for now. Let's just say that we have years’ worth of plans for Lord of the Rings Online; stories to tell, lands to explore, and heroic deeds to be done.
It remains an honor to be your Executive Producer, and we thank you again for your support.
