Blizzard has a short little FAQ up at http://us.battle.net/wow/en/forum/topic/2456449381 for the new Dungeon Journal that’s coming.
It’ll be pretty convenient being able to see and read about each bosses’ spells, abilities, and phases from within the game itself before engaging them, but it won’t be spelling out specific strategies though. You’ll still have to learn (or read) about that on your own.
You also get loot lists for everything in there, but there’s no mention of the trash getting similar treatment in regards to their spells, so it looks like I’ll still have things to write about after 4.2!
