This morning, Sega announced its upcoming plans for Gamescom which takes place later this month in Germany. While most of what the publisher will be bringing to the convention is to be expected, there was one teaser for an upcoming announcement that stood out.Sega said via press release today that it will be announcing a new game later this month. It says that this is "an all-new AAA game that has yet to be revealed to the public." For those that attend Gamescom, Sega also confirmed that this new mystery title will be available at the company's booth alongside Catherine: Full Body, Two Point Hospital for consoles, and the SEGA Mega Drive Mini.As for just what this new game could be, well, it's kind of hard to say. Sega has an extensive list of properties that it owns, so if it's the return of an IP from the past, then it's really difficult to pinpoint just what that could be. Conversely, perhaps it will be an entirely new franchise altogether.The only thing we do know for certain is that this game's reveal will likely take place on Monday, August 19 during Gamescom's opening ceremony. The Dorito Pope himself, Geoff Keighly, just released an announcement about the opening show and said that Sega will indeed have a reveal to make during this time.Gamescom 2019 is set to take place later this month from August 20 until the 24th. We'll obviously let you know what this new Sega game is exactly once it's announced.
