We have tons of patch 4.3 news today, from previews of Transmogrification, Void Storage to the Gilneas Reputation Mounts, Dungeons. Now, we are given a sneak peek at the raid: Dragon Soul for World of Warcraft patch 4.3, where heroes from the Alliance and Horde will face off against Deathwing himself.

The raid begins at Wyrmrest Temple. All of the aspects are all there, ready to deal the final blow. But first you should face off against six bosses, and then two encounters against Deathwing.

Let’s take a look at six bosses:
Morchok—once a passive guardian—is now convinced that his only respite will come with Azeroth's demise. Morchok rages against the foundation of Wyrmrest Temple, Azeroth's last beacon of hope in the Hour of Twilight.

Warlord Zon'ozz and his soldiers waged endless war against the forces of C'Thun and Yogg-Saron. Millennia have passed, but the warlord still serves the chaotic might of the Old God N'Zoth. Deathwing has now unleashed this legendary faceless one to crush the defenders of Wyrmrest Temple.

Yor'sahj the Unsleeping has eagerly assisted Deathwing, providing the Destroyer with the means to release more faceless ones from their prisons deep beneath the earth. Their numbers are endless and their power is beyond reckoning, and Yor'sahj intends to reap a grim reward for his faithful service.

Hagara the Binder, one of the first students of arcane magic under the Forsaken, showed surprising potential for one who had started learning so late in life. But in her undisciplined attempts to bind elementals into servitude, she was ensnared and twisted by the Windlord, Al'Akir. Now fiercely loyal to the Twilight's Hammer, Hagara binds others for her elemental masters to torment.

More an abomination of dark energy than a dragon, Ultraxion has spent his short life absorbing the essence of captured nether dragons. Ultraxion is the only twilight dragon Deathwing has praised, and his arrogance is overshadowed only by the crackling energies surging through his twisted form. Loyal to his master, Ultraxion swears to bring about the fall of Wyrmrest Temple.

Though once vast in number, only a few dozen twilight dragons now remain. Astride these hardened survivors are the last vestiges of the Twilight's Hammer's army: the elite drake riders of Deathwing's personal escort. Led by the insidious Warmaster Blackhorn, they move with unholy purpose, driven to protect their dark master.
When Deathwing first channeled the Dragon Soul's power against the other dragonflights, the massive energies that he unleashed threatened to break him apart. Rather than forgo this weapon, he had adamantium plates fused to his scales to hold his body together. Later reinforced with elementium, these plates are now his weakness—the sole vulnerability to Deathwing's lethal presence.

Finally, players will take the fight to Deathwing himself, landing on his back for the first part of his encounter and then attacking him in his final form on the edges of the Maelstrom.
