In the upcoming patch, players in Inferno will receive a stackable buff called 'Nephalem's Wrath' which will increase players hp/damage/resistance by 10% per stack. Every week starting from the release of the patch, this stack will be increased by 1. Please note that you can deactivate this buff by speaking to an NPC in town.

King Varian Wrynn and Garrosh Hellscream show up to offer their "blessings"

With the 3.3.3 patch around the corner, raiders in Icecrown Citadel get the blessing from their respective commanders to boost health, healing and damage. Get more details after the break ...

When players logged in to World of Warcraft on Tuesday after the server reset, raiders in ICC found a new presence in the entry hall. King Varian Wrynn for the Alliance and Garrosh Hellscream for the Horde were on hand to offer buffs to raiders ready to make their way to the Lich King.
The new buffs, called Strength of Wrynn and Hellscream's Warsong, offer 5 percent buffs to players in health, healing and damage. However, talking to Wrynn or Hellscream gives you the option to turn the buff off if you wish to continue with the unnerfed experience.

There are plans for more buffs in 5 percent increments, up to 30 percent, but there is no timeframe yet for those to be implemented.

During the scheduled server maintenance on the week of March 26, the “Power of the Aspects” spell will grow more powerful, reducing the health and damage dealt of all enemies in the Dragon Soul raid by 15%. This spell will grow progressively stronger over time to reduce the difficulty and make the encounters more accessible. The spell will affect both normal and Heroic difficulties, but it will not affect the Raid Finder difficulty.

Don’t need the help of the Dragon Aspects? The spell can be disabled by talking to Lord Afrasastrasz at the beginning of Dragon Soul.

We hope you continue to enjoy Dragon Soul, and that these changes encourage you to attempt a higher difficulty, or just keep pushing to down that next boss.

Only speculations though ROFL

prolly implementing soon at the cost of some US dollars
