"The next MoP update is planned for next week including important spell fixes such as Rain of Fire, Health Funnel, slows duration in PvP and more. It will also include the reimplementation of the last boss in Gate of the Setting Sun, Raigonn, as well as the re-opening of Siege of Niuzao Temple and more Raidfinder bosses in Heart of Fear. Additionally, seven out of eleven Throne of Thunder bosses already have heroic mode scripted, however, the four remaining will not be fully working before the update to 5.4.8. We have not yet decided whether we will release partial heroic mode with the next update, but if we decide to do so it will be announced ahead of time. Furthermore we are currently working and finishing three new bosses in Siege of Orgrimmar, including the Fallen Protectors, Norushen and Sha of Pride. They will be released without loot as soon as they are ready to avoid imbalance in the current item progression."
