Sorry I know it's on the wrong forum, waiting for a mod to change it to Diablo General Discussion.
MMO-Champ said it wasn't confirmed by Blizzard that it even exist but here is my reaction when I read the line in bold:
Diablo
Diablo III had a second expansion that was canceled.
Blizzard says cancellations show commitment to quality and that they have only released about 50% of the projects that they have worked on in the past 3 decades.
Project Hades was reportedly a Diablo game in development that would be more like Dark Souls, an over the shoulder dungeon crawler that was also canceled.
Project Fenris is the current incarnation of Diablo IV and the team is optimistic about it. Their art direction is to embrace the darkness.
Project Fenris is still early in development and will likely not launch until 2020 or later.
They still claim that there was talks to announce Diablo IV at BlizzCon, but it wasn't far enough along in time, yet one dev disputes this.
Blizzard is careful to announce games before they are ready now because of what happened with Project Titan.
Project Fenris is being worked on by a separate team from Diablo: Immortal known as Incubation.
Diablo: Immortal exists because they heard that China really wanted a Diablo mobile game.
NOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO OOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO!
NO!
OH LORD NO!

Your thoughts? I for one tend to think it would have been awesome.
