Some Updates Are Arriving on June 20:
(New) Titan Rune Dungeons-Defense Protocol Beta
Embrace the challenge of Titan Rune Dungeons, where you'll take on a new higher-level difficulty in which creatures and bosses have a variety of dangerous new effects as well as additional health and damage. Bosses killed with Defense Protocol Beta active award loot from the 10-player version of Ulduar. The final boss will also award a new currency: Sidereal Essence. Sidereal essence may be exchanged for rewards from 10-player Hard Mode Ulduar gear at the Animated Constellation vendor in Dalaran.
Titan Rune dungeon is a new difficulty that is available for each of the existing WotLK heroic dungeons. It would be great if you could release Titan rune difficulty for the original vanilla dungeons.
The gear would be 10-man Ulduar level (catch-up gear) with a few rare ToC level items in the end-game dungeons like strath/ubrs/scholo that you will overturn, so they're difficult to keep everyone interested.
Trial of the Champion
Head to the Crusader's Coliseum at the Argent Tournament to begin the challenge in this 5-player dungeon.
Trial of the Champion only has one quest available for it, the Heroic daily quest Proof of Demise: the Black Knight.
It is a really good dungeon. It does have some cool mechanics, like having someone spell 
Hammer of Justice, and then they can throw a beast Hammer back at the boss or a good old quick face away from the boss mechanic before it finishes, and then the last boss be in the Black Knight, which is a two-phase fight with lots of Explode Ghouls, which is always fun to watch people that just turned into a really comprehensive dungeon guide.
The Argent Tournament
Join the Argent Tournament to undertake new quests and daily quests while showing off your jousting prowess for new rewards.
Wrath of the Lich King PvP Season 7 Begins
Three Big Dungeons Will Open on June 22:
Trial of the Crusader and Trial of the Grand Crusader: Undertake the challenges of the Trial of the Crusader and Trial of the Grand Crusader 10 and 25-player raid.
Level 80 Onyxia's Lair: Face Onyxia in her Lair in the level 80 version of this encounter
Trial of the Grand Crusader is the heroic mode version of Trial of the Crusader. These are the hardest raid encounters before Icecrown Citadel. A major difference between Trial of the Crusader and Trial of the Grand Crusader was the Argent Crusade Tribute Chest.
Onyxia's Lair is a level 80 raid dungeon located in the Wyrmbog, Dustwallow Marsh. The level 80 version of Onyxia drops headpieces with similar names and models as the Tier 2 ones the original level 60 version had. She also drops a new version of 
Quel'Serrar.
