The first half of Dragon Soul is now testable through LFR. If you're level 85 and have an average item level above 365, you will be able to queue for the Siege of Wyrmrest Temple. The second LFR entry for the later half of the raid is not yet available.

This is VERY much a work in progress, the UI is in an unpolished state right now. Give it a try though!
