Diablo III Patch 2.1.0 Goes Live 'This Month'
Details at gamescom on the PC 2.1 patch, and 'Ultimate Evil Edition' updates

The interview starts with talk about Blizzard's large presence at gamescom 2014, and then at 2:45 in the video, Mr. Hight gets into details about Diablo III patches and development.
- "Later this month", Diablo III patch 2.1 will be released.
- Fairly soon after patch 2.1 comes out for the PC Diablo III, a lot of the 2.1 content will be released for the PlayStation 4 and Xbox One versions of the Ultimate Evil Edition. The consoles will receive features from 2.1 including Greater Rifts and the Treasure Goblin realm area of The Vault. Seasons and leaderboards will not be transferred to the consoles. Those features were "designed more for the PC side of gaming, but everything else is going to come across".
- Season 1 will start in patch 2.1. They haven't officially announced how long the seasons will be, but that info will be released when the season opens. "We want to make sure we give people enough time to build up their character, but not too much time; we want it to be competitive." (In a recent Korean interview, lead content designer Kevin Martens suggested that the first season may last 2-3 months.)
- There will be more content updates for Diablo III, after patch 2.1.
With the Ultimate Evil Edition coming out this next Tuesday, that only leaves August 26 in the month as a possible patch day. Unless there a delay, patch 2.1.0 will go live that Tuesday.
