Ladders - The idea of a seasonal ladder (much like the feature in Diablo 2) was mentioned positively by both developers. It is clearly a big feature that wouldn't be added in a standard patch; Wyatt Cheng stated clearly, "It wouldn't be viable until an expansion." He delved into the two main positive aspects of a seasonal ladder: the competitive race to the top, and the economy reset. He later stated that if seasonal ladders were implemented, they would function much like Diablo 2, where existing non-ladder characters would stay and new ones could start in the ladder mode. Travis Day talked about how ladders could increase Diablo 3's longevity, even years from now, once Blizzard isn't actively adding new Diablo 3 features and has moved on to other games like Diablo 4.
So I assume the ladder is something that you would be excited about, but something that also is a little loaded?
Wyatt: We're definitely looking into the possibility of a ladder, or something like that. I personally -- this is just me speaking and there are other people on the team who would disagree with me, so I'll say that, it's just my opinion -- I'm more excited about the reroll and clean economy aspect of ladder seasons, than I am of the race. I know the race is exciting too, and there's pictures of people who are getting ready for the new season. They have all their caffeinated drinks on their desk, and I think that's epic and awesome, if not always healthy. But realistically, yeah it's something we're cool with. It wouldn't be viable until an expansion.
...That's really important and it's really compelling, and we probably want to have that one day (ladders), but I don't know how we'll implement it, or what it'll look like, or when it'll go in....
a ještě tam oficiálně potvrdili Diablo 4, takže komu nesedla trojka, může se těšit na 4ku

Travis: I totally just confirmed D4, totally did. I guarantee you, at some point in the history of Blizzard, there will be a Diablo 4. It'll probably be 20 years from now, it's no time soon. But I don't think it's too much of a reach to think that the company that has 3 really strong IPs is going to make more and more of the games in those IPs.
