Diablo 3 - 7 Development Points

MMOSite has a summary of an interview with Blizzard's Jay Wilson, where he explains they identified seven key points for the development of Diablo III.  Here's an excerpt on RPG elements:

Jay Wilson expressed, Diablo III is designed to redefine the gaming experience of Diablo series. Diablo I and Diablo II emphasized action scenes, but Diablo III intends to strengthen the game's depth so as to make it a better and more profound RPG. As the previous Diablo installments paid attention to action performance instead of role playing, the developers hope Diablo III can make progress in presenting the role-playing elements and absorb the essence of Diablo I and Diablo II at the same time.
