Throughout a game’s PR and marketing campaign, the publisher or developer needs to create promotional screenshots to show off a game’s visuals. It’s important to note that the final polishing of a game — those extra steps that take the game to final quality — often isn’t done until the last few months of the project. That will vary, of course, from one game to another, as some teams may aim to be “art complete” much earlier in development. Anyway, these shots will usually be created with whatever game content is available — so if a game is being announced two years before its release date, there’s a good chance that the aforementioned game content is not final, only partially available or completely non-existent.
