World of Warcraft's original races will get a visual overhaul with the game's next expansion, Warlords of Draenor, Blizzard announced at BlizzCon today. Some of the first remodeled characters shown were the male versions of the orc, dwarf and gnome, which you can see in the gallery above.
According to Blizzard, the visual upgrade for character models is an effort to bring the original races up to the fidelity of the Pandaren, which were introduced as a playable race in World of Warcraft: Mists of Pandaria. The developer said it is striving to "keep the soul of the original characters" and "make sure [they] still look like what you know, just better."
In addition to a higher polygon count and improved textures, character models will get refined animations, and new details like teeth, tongues and facial emotes. Blizzard said it plans to increase graphical fidelity "across the board," improving the look of NPCs, objects and environments in Warlords of Draenor.
Update: This post originally said that the screenshots showed the male troll; they show the male gnome instead.
