"We’re preparing a pretty hefty show, weighing in at around 20 minutes and sporting a fresh new look. And we’ll have some great news to share with you, including new game reveals, new content from PlayStation’s Worldwide Studios, and a host of other updates."
Don't know what to expect really but we are going to definitely see something on the Last of Us Part 2 as there is a media event next week for the game. I would guess trailers for COD, Medievil, Concrete Genie and maybe Ghost of Tsushima (i pray).
As for new announcements:
Maybe a Ape Escape remake
A new VR game
