Status: Unannounced, but in development
Guerrilla Games is a huge studio, packing over 400 employees these days. While it’s likely working on a sequel to Horizon: Zero Dawn, then, there’s also strong speculation it has a new multiplayer project in the works. The Dutch developer re-hired the director of Tom Clancy’s Rainbow Six: Siege to work on an online-focused project, and given Sony’s vocal interest in multiplayer games, it’s likely that this will be a PS5 launch title designed to fill a hole.
Status: Unannounced, but strongly rumoured
We know that Warner Bros resurrected Avalanche Software to create a AAA title for consoles, and we also know that at one point it was working on some kind of Harry Potter-themed role-playing game. Prototype footage of the title, showcasing a character creator among other things, leaked online a while back – and the studio has continued to aggressively hire ever since. Given development schedules, it’s likely that this will be at least cross-gen – assuming it is still in production, after all.
Status: Unannounced, but an educated guess
Developer Guerrilla Games is hard at work on something, and you don't have to be a genius to assume that the project in question is a sequel to Horizon: Zero Dawn. The new IP was a smash hit on PS4, and the studio's reputation for pushing hardware limits makes the hypothetical Horizon: Zero Dawn 2 a strong candidate to show off the upgraded power of the PS5. Whether it'll be a next-gen launch title is up for debate, but we wouldn't be at all surprised.
Status: Announced with no platforms specified, but strongly hinted to be a next-gen title
The Elder Scrolls VI is years off, and that means it's almost certainly going to be a PS5 game. Publisher Bethesda has made a habit of announcing its games relatively close to their release dates, but with this one, its hand was somewhat forced at E3 2018 due to swirling speculation and the fact that it had to keep fans happy after talking at length about mobile titles.
Status: Announced for PS4, but given development progress, an additional PS5 release seems plausible
Just like Death Stranding and Ghost of Tsushima, it's not hard to envision The Last of Us: Part II as a cross-gen title. Another PS4 game that's settled with a long development cycle, developer Naughty Dog's pedigree is abundantly clear, and Sony will want to ensure that this sequel releases at exactly the right time.
