Della Bitta confirms, also, that Blizzard is still interested in letting players watch the matches, either via television or some other way (we heard that way back when from WSVG's President -- when they were still around, anyway). And Joong Kim lays out a simple timeline for the Arena tourney: Blizzard expects the online portion to be finished mid-July, and the Global Finals will start later in the year, around October (which is when another big Blizzard event is taking place... coincidence?).
Wong doesn't get Kalgan to list a favorite class (obviously -- think of the torment that would cause on the forums), but he does confirm yet again that Blizzard isn't giving up on keeping both the PvP and PvE games the same. They want players using the same abilities as much as possible in both types of gameplay, and apparently they're committed to juggling both of those flaming torches for as long as they can.
