That just happened.
"The latest class revealed for ArenaNet's Guild Wars 2 is the Ranger, a bow-using, pet-charming, trap-setting class that might just out-hunt World of Warcraft's Hunter class.
The Ranger class answers a question many players have been bugging ArenaNet with since the first reveal of Guild Wars 2: Will the game feature pets? The answer is a resounding yes, with a Ranger pet charming skill that expands upon the system used for the Hunter in Guild Wars the first and the Hunter class in World of Warcraft.
Rangers can charm any of 12 different types of pets in Guild Wars 2, from bears and spiders to more specialized species, such as sharks. Each species has sub-species with different abilities. A brown bear has different skills than a polar bear, for instance.
Pets in Guild Wars 2 will share the same level as the Ranger, but they also climb a 20-rung evolutionary ladder, eventually developing skills slots the Ranger can use to add special abilities to their pet, tailoring them to fit the player's tactics. The Ranger can keep three pets at a time, switching them out during downtime or using special skills."
