Turbine has officially announced the launch date for the
Lord of the Rings Online's Update
5: The Prince of Rohan. It will be going live on Monday, December
12.

Update 5 will be bringing a number of new things to the table: the
Isengard instance cluster (discussed in our Play
Session with the Devs), the Instance Finder (discussed in our Instance
Finder article), consolidated currencies (discussed in our Currency
Consolidation article), a short-but-crucial continuation of the epic
storyline and a number of tweaks and such for existing classes and
content.

The Instance Finder in particular has been a hotly-debated subject, and
Leo "Ransroth" Zelevinsky has addressed a number of questions in his
Q&A-style Instance
Finder Developer Diary. We can likely expect more dev diaries over
the coming days.

Turbine has also released 5 new official screenshots of the new 6-man
instance, the Foundry. According to the press release:

Powerful and mysterious weapons have been appearing in the hands
of soldiers under Saruman’s command. Infiltrate the Foundry, the sprawling
subterranean heart of Saruman’s war effort, and disrupt the supply of the
dangerous weapons to deal a fateful blow to Isengard!

The screenshots all seem to focus on a Burglar soloing the 6-man
instance, but do a nice job of showcasing the trolls, orcs and atmosphere
of the space as well.
