Blizzard went rather quiet after BlizzCon but we know there are other Diablo projects in the works. A further post from Blizzard today reiterates that.
[BLUE]We continue to read feedback and our internal discussions are ongoing. We have many plans for Diablo across multiple projects which we’ll be revealing over the course of the coming year. We are eager to share more about all of our projects, but some will have to wait as we prefer to show you, rather than tell you, about them. It’s going to take some time as we strive to meet your expectations, but now, more than ever, we are committed to delivering Diablo experiences the community can be proud of.[/BLUE]
