The developers at Blizzard posted a new blog entry on the Diablo side of things discussing the future updates coming to Diablo 3. The blog is pretty short compared to other updates, but it gets to the core of a few things in the game. Basically, they're going to continue with more content in a seasonal form while offering patches to help things run smoothly. Not to mention a commitment to taking feedback from players at the PTR servers. The comments section, of course, berated them with cries for Diablo 4, but what else is new. Here's a snippet from the post.
One thing we've been asked for is to clarify what our plans are, what (exactly) we're working on, and where the future will take us. This blog is one of our first steps. More frequent presence and interaction from our community team on our new forums, especially around patches and PTR cycles, is another. We want to be able to talk and interact with members of our community around the world on a regular basis about the thing we love that brings us together: Diablo.
We hope we've provided you a better idea of where we're at with Diablo III. In the meantime, we want Sanctuary to feel like home to all heroes, so you can return whenever you have the itch to slay monsters, don powerful Legendaries, and always find something a little new.
