Geoff Keighley's Summer Game Fest has updated its schedule once again, confirming that it will be hosting a "special event" tomorrow. In response to curious fans on Twitter, Keighley has revealed that the event will be "one of the more important moments this summer."
For now, the website just says to "tune in for a special Summer Game Fest showcase and interview with Geoff Keighley," which will take place at 8am PT / 11am ET / 4pm BST on May 13th.
No clues have been provided as to what it could be, and who knows - maybe it's not a game reveal at all? In the meantime, Summer Game Fest is hosting another surprise game reveal later today at 9am PT / 12pm ET / 5pm BST, which Keighley says will be a "cool and fun" title.
