Blizzard has just created a new gallery on their main website for Concept Art. The art includes many recent works, along with classic pieces from StarCraft 1, WarCraft II, and the Diablo series. Although not containing any never before seen art yet, this site is a great tool for lore enthusiasts. If you're in the market for some new desktop wallpaper, this would be a great place to look.
