Diablo type RPG where you play as an Inqusitor. Looks like there are different Inquisitor classes and there's a sandbox star map for you to roam around in. Has execution animations and fully destructible environments. Can play single player, or up to 4 player co-op similar to Diablo, however the main campaign missions are solo only (somewhat like Destiny).
So far I have seen a Crusader and Death Cult Assassin as playable classes, with the third not yet revealed.
Also, Xbox, PS4 and PC so everyone can look forward to it - bar Nintendo scrubs - though it's a 2017 game.
