E3 2018 starts in a little under a week, and ahead of the massive showcase, Sony has released an announcement schedule on the PlayStation Blog leading up to its press conference on Monday, June 11. Starting Wednesday, June 6, Sony plans to announce three new games, a release date for an upcoming game (more than likely a PlayStation 4 exclusive), and details of "An Eagerly Anticipated Game [Coming] to PS VR," each being offered once a day for the next five days, effectively concluding on Sunday, June 10. From Wednesday to Sunday, each announcement will be held at 8 AM PT / 11 AM ET (4 PM BST), as we join Sony for its countdown to E3 2018.

It's difficult to say what those three new games could be, as a few of Sony's studios are already working on named projects: Bend Studio is working on Days Gone, Japan Studio is supposedly working on Astro Bot: Rescue Mission, London Studio is working on Blood & Truth, Media Molecule is working on Dreams, Naughty Dog is working on The Last of Us Part II, and Sucker Punch is working on Ghost of Tsushima.
