Hellz yeah! This might actually renew my interest in Diablo III! These are great news.
Also, you said you've reinstalled SC2 recently. Care for a game or two some time? ;)
Btw if you're more interested in the game, I wrote a giant essay on SC2 recently - with pictures, videos and everything! If you're a fan of the game and are willing to, check it out and react to it, I've been hungering for some StarCraft people on this site!
