Interview with the dev's.
Sounds like Turbine is doing with Lotro what they did with AC. ie. a constantly evolving storyline. If its like AC, then players will effect the overall happenings in the "world" as well. But who knows.

LotRO players "should expect to see multiple updates in a year, separate from expansion packs - just more content for their subscription."

Also, a guild has cleared the first end-game raid instance. Everyone else is whining about how impossible it is.

And the chicken chasing, dance comp, pub crawl mini patch wasn't as queer as it sounded.
