First, the rogue legendary is actually a pair of legendaries -- specifically, a pair of daggers named the Fangs of Father (which may be a mistranslation), according to Taiwanese Gamebase. GC explains across his interviews that rogues have understandably felt left out of this expansion both in terms of numbers and content, so giving them a legendary of their own was a good way to get them into the spotlight. The quest line for these daggers will revolve around the single pure black dragon egg that players helped protect in the Badlands. The dragon will hatch (it's a boy!) and lead rogues on a time- and gold-consuming quest around the world for their well-earned blades.
GC also discussed the Raid Finder, which will take advantage of an entirely new raid difficulty. Blizzard estimates the difficulty as somewhere between 5-man heroics and normal-mode raids, with the gear filling the same gap. Raid Finder instances are not planned to lock you out of normal or heroic raids.
Speaking of raids, melee classes will get a buff in the Deathwing raid to compete with ranged classes; think of it like a melee-exclusive ICC buff. Also, epic gems will finally make their appearance as drops in the Deathwing raid.
