And yes just as everyone suspected is a mobile game.
So much for a remaster of D2
Diablo 4

They did also announce a remaster of Warcraft 3 as well as the WOW classic server will be up summer of 2019.

Judging from a vast majority of comments most have zero interest in a Diablo mobile game.

I'll post my impressions of it a little later. Just got home and in a little bit of a rush to make it to my cousins wedding in a few hours.

Early preview, I didn't like it.
