Gears of War developer Epic Games is planning to make a big announcement next week, according to a post made by Mark Rein on the game's official forum.
That's all we know for now, although the suggestion that it's Gears of War's specific release date seems to have been pooh-poohed a bit by Rein himself.
When someone said, "it's gotta happen sometime right?", Rein responded: "Sounds like maybe the announcement that is going to be made isn't what you think it is."
So, stay tuned. Along with Gears of War, Epic's also working on Unreal Tournament 2007.
