To bring a Jagex quote (from MMG) to the topic...
We can't give you a release date at the moment because large complex game development projects such as this one are extremely hard to estimate. The last thing we want after spending so much time and energy on this project is a rushed release, which is why we won't launch it until we are confident that it is ready

When is the new title coming out?
One of the biggest problems with MMOGs these days is how rushed they are launched, invariably letting players down due to excessive bugs or half-baked design decisions. We want to make it right, fun, huge, amazing. When it has all these ingredients, we'll invite you to try it out and tell us what you think of it. Forget about any dates you might have heard for its launch, we're not bound to them but to quality and excellence. The game will be released when we feel it has reached maturity, as simple as that.
