Birthright of the Dwarves has been OSRS Gold released just a few days ago. It is supposed to be an interesting and difficult adventure. Haven't completed it yet because I don't meet the requirements, but most people are having a hard time with the boss fight(s).

Jagex is currently working on two more quests "Missing Predicted Death" is an adventure that involves Sliske and Itchlarin as in addition to Death (as seen in the Grim Reaper). It will focus on Sliske's "rivalry", which is not the best word since it's not an actual rivalry given Itchlarin's power up until recently. Let's declare that Sliske dislikes Itchlarin quite a bit.

It's a quest that can be considered the continuation of The World Wakes because we'll finally find out if Sliske became a God or not and what he did to acquire the staff of Armadyl. While I was told that they're working on a different quest, I can't recall what it is. It was interesting to me.

Prifddinas is an ancestor of the Iorwerth clan. This Zamorakian elven clan was a shambles to Seren and took over after a brief civil conflict. I am convinced that Seren will return when there is a return of the Gods. We'll also have a grandmaster quest focused on liberating the city from Iorwerth clan. It's only a matter time.

While I do agree with the majority of your comments, I think that the lack of new quests is likely to be a problem very shortly. The return of Buy RS3 Gold the Gods opened a whole new world of possibilities. And we have the World Events too, I discovered the Battle of Lumbridge an awesome event can't wait for the next one.
