Call of the Crusade

The lastest major content patch 3.2.0. called "Call of the Crusade" went live August 4th, 2009 this tuesday.

Here is a small extract from wowwiki:
Since the opening of the Argent Tournament in northeastern Icecrown, adventurers have journeyed from across Azeroth and beyond to prove their worth in the heart of the Lich King's domain. Under thundering skies the tournament's participants hone the arts of war and face off in bone-shattering jousting matches to earn the right to be called champions. Yet these heroes have yet to face the greatest challenge of all: the Crusaders' Coliseum. Formidable Horde and Alliance champions, ferocious beasts, and Scourge lieutenants are just some of the opponents awaiting adventurers in this gladiatorial arena. Few will survive the coliseum's perils, but the Argent Crusade is confident that the worthy heroes who do emerge victorious will be ready to join the offensive against Icecrown Citadel and end the Lich King's reign of terror.

Those who have played WoW recently will know that the Coliseum was underconstruction and provided many daily quests. Finally, the construction is done and new instances and raids are open.

Trial of the Champion
5 player (normal and heroic mode) dungeon.

Trial of the Crusader
10 and 25 player (normal mode) raid dungeon.

Trial of the Grand Crusader
10 and 25 player (heroic mode) raid dungeon.
Crusaders' Tribute: Active on heroic difficulty only, the tribute system will limit players on the number of attempts the raid is allotted each week. Additional rewards can be earned depending on the number of attempts left in the tribute run each week when the final boss is defeated.

This new Crusaders' Tribute is a new system which will prove to be an incentive for higher ranking guilds. I forsee this being implemented into future raids as well.

Also, a new battleground has been released called "Isle of Conquest". Apparently it is a 40 vs 40 bg and somewhat like Alterac Valley and Strands of the Ancients combined together.

Other interesting points to take note of are:
The newly implemented battleground experience points
New Druid Shapeshift Skins
A new zeppelin docking ramp has been added to Thunder Bluff allowing Horde players easier transport to and from Orgrimmar.
And other things added for extra conviniences
