It's been a little over a year now since Dave Anthony and Jason Blundell announced Deviation Games & their partnership with Sony. We don't know much about what their game is, so it's still very much shrouded in mystery. I reckon we're also a while out before getting a proper reveal, but that only allows folks to become more intrigued by the project, making them wonder what it could be.
Some time ago I did a research on their LinkedIn job offers and found this:
I'd say it will be a PS5 exclusive Unreal Engine 5 2026 big ass AAA action MMORPG (pretty likely shooter) new IP, focused on online multiplayer but with single player story campaign and coop. It would feature a persistent world, quests, missions, ballistic weapons, vehicles and Sony-like properly animated cutscenes and characters.
Since late 2019, add at least a year for building the team and make preproduction, plus an additional 5-6 years of production, maybe more due to covid, being a new IP and the first game of the studio, don't expect their first game to be relesed until at least late 2025 or 2026. If it gets a delay pretty likely they'll give them some extra time on top and will put it as PS5/PS6 crossgen PS6 launch game.
The leads of the studio and many people more from the team (they have over 120 people in LinkedIn) come from Treyarch/CoD (mostly BO but also the other ones) or Blizzard (they also hav Diablo and WoW producer, to name one). Most of their staff are senior devs who worked in other top AAA games in places like Ubisoft, Respawn, Infinity Ward, Splash Damage, Firaxis, DICE, Rockstar, ID Soft, Bethesda, Ready At Dawn, Insomniac, Sucker Punch, ND, SSM, EA, Skydance, Remedy, The Coalition, Turn 10, 343, plus a few animators from Dreamworks or Disney. Top tier studio.
