Its been awfully quiet from blizzard. They announced a new patch for over a week now? Still nothing even datamined, that concerns me. I think blizzard is too busy atm with gamescon. I keep my thumbs up and hope for a quick notice but i doubt we see season end within 3 weeks from now :'(
Blizzard has different teams for different projects, so they can't be busy with gamescom (not gamescon) since they are not going there. From devs to community managers, through their game site, there is no reason to think their silence if we can call it that, is due to a conference they are not attending to. To put this in perspective, even if they announce two new games, this still doesn't justify not working on a total different game since that game has a dedicated team that has to work. But since the patch is still in production and testing, this season has to end and the new one to start, we know they still work on the game at least until Blizzcon, where, hopefully, more new Diablo 3 stuff is revealed. Not to mention that as soon as the next season starts, the next one has to go into production.
