Arkane Studios' next game isn't another Dishonored, it's a new property called Deathloop. It should still feel familiar, though.
Bethesda announced Deathloop at its E3 press conference with a stylish cinematic trailer (embedded above). It pits two rivals, Colt and Juliana, against each other; Colt wants to destroy the Blackreef island and Juliana wants to save it. They're stuck in a time loop, murdering each other over and over.
Here's the official description: "Deathloop transports players to the lawless island of Blackreef in an eternal struggle between two extraordinary assassins. Explore stunning environments and meticulously designed levels in an immersive gameplay experience that lets you approach every situation any way you like. Hunt down targets all over the island in an effort to put an end to the cycle once and for all, and remember, if at first you don't succeed… die, die again."
However, Arkane says Deathloop has the signature studio gameplay that people love about Dishonored. It's a first-person action game. Levels are designed so players can choose their approach -- presumably stealth, non-lethal, etc. Arkane knows what it's doing, so Deathloop is the sort of project that's immediately intriguing.
