This is a little late, but Blizzard has updated their Class Page on their upcoming MMORPG World of Warcraft. Heres a snip of the Rogue class, my favorite!
"At home in the shadows and skilled at disappearing from sight, the Rogues of Azeroth are most comfortable when acting in the background. Twisting events to their favor, striking only when advantage is greatest: this is where a Rogue excels. With their cunning tricks, physical abilities, and mastery of concealment and disguise, Rogues have no trouble finding employment as thieves, cutthroats, spies, and assassins. "
