Not much is known about the next three fights, but they come out on Tuesday. One is Sindragosa and the other is the "Heal Valithria Dreamwalker to full" fight. I'll post what I can find here, read up so you can get a head start on Tuesday when we decide to take these fights on.

For this fight, healers must heal the green dragon to full. Adds run in and will try to stop you by channeling reduced heal debuffs on her, attacking healers, etc.

Sindragosa tactics wowwiki: http://www.wowwiki.com/Sindragosa_%28tactics%29

A mixture of Sapphiron, Onyxia and Sartharion. Typical dragon fight with frost tombs and ice bombs.

As for the Lich King....for right now, we're on our own.
