A post on the Diablo III Website has more on planned changes in the upcoming version 1.04 patch for Diablo III, outlining how they will change the Legendary items in Blizzard's action/RPG to help them better live up to that label. This includes the addition of new affixes and they go on to describe their hopes that this will introduce more build diversity to the game. They also explain the ill conceived planning that made legendaries "kind of crappy," and how they are looking to de-crappify them going forward. They also talk about how this will impact set items (which are also legendary items themselves), and offer this video showing how the artists have been working to make these items have cooler appearances.
