People need to calm down. They have a Diable game for mobile big whoops. That does not mean there wont be on for consoles and PC.
No, you're missing the point. The problem is not that there's a mobile game coming of Diablo; there wasn't this massive outcry at Elder Scrolls: Blades. It's that Blizzard thought that it was a good idea to make it their main announcement of the first night of Blizzcon. That's like serving a hog roast at a Bar Mitzvah. Diablo fans paid their attendance fees and all the associated costs of going to a Con in the reasonable expectation that their I.P. was going to be the main feature this year only to find out that the Diablo announcement was something that none of them would play.
