Most importantly, the website will reveal detailed information on each of the five new hero classes for the game. To start off is the Demon Hunter , as seen in the trailer posted above. Should you feel the need, you can even design your own in-game banner and use it towards unlocking sigils.In fact, Blizzard says that it will be having an art contest for some pretty sweet hardware prizes. For Blizzard to provide a detailed teaser only tells me that Diablo III is going to be one heck of a unique gaming experience.
