Ghost of Tsushima might come to PC
As you can see the "Only On PlayStation" logo has been removed from the box cover. PlayStation already did the same thing for Days Gone and Horizon Zero Dawn since both titles have moved from PS4 exclusivities to PC. Thus, it makes sense that the Sucker Punch's title will have the same fate.
Furthermore, Sony didn't use the "Only On PlayStation" logo for PS4 games that also have a PS5 version, such as Spider-Man: Miles Morales and Sackboy: A Big Adventure. Titles that are exclusive to PS5 also don't have the "Only On PlayStation" label, such as Demon’s Souls and Ratchet & Clank: Rift Apart. Thus, we can also speculate that Ghost of Tsushima might get a PS5 version.
However games like The Last of US 2, who is also coming to PC, still have their PlayStation exclusivity written on the box cover...
Is Ghost of Tsushima coming to PC? Only time will tell.
