I didn't see this posted yet and it was just published today.
Topics covered in this interview include:
1. Shared Replay Viewing
2. Improving the Ladder experience for new users. Addressing Ladder Anxiety: Dustin Browder goes in depth to talk about some of the problems with SC2's WoL Ladder system and elaborates on a lot of the training modes being added for new users coming from the campaign.
3. New improvements to the UI editor to make it potentially easier to use.
4. New function for replay viewing to allow casters to customize what stats are displayed while viewing.
5. Resume from replay.
6. Clans/Groups for HOTS.
7. No plans for automated tournaments just yet for HOTS, but Dustin Browder says is an idea they "Definitely" want to add in for Legacy of the Void, has heard all of the enthusiasm people have had towards the idea.
Personally I think this is a really great interview. I'm very happy that Blizzard is so focused on improving the ladder experience for new users. I think it shows they are paying attention to a lot of the community based feedback we've been throwing at them about B.NET 2.0 over the past 2 years.
It's been really tough to try and get some of my friends to convert over to SC2 from other games for a lot of the reasons DB talked about.
The new training mode, ramped up AI difficulty and unranked play should do a TON to further this game for the casual fanbase.
The UI changes for HOTS have been great, I can't wait for them to unlock a lot of the new features DB talked about that we don't have access to on beta yet.
Shame that no automated tournaments are coming for HoTS. That was something I really loved about WC3's B.NET interface. Even if I only participated a few times it was a great thing to see happening always felt like there was something going on.
