When will we get our first real look at From Software’s anticipated Elden Ring? Of course, a few brief, blurry seconds of the game leaked last week, but it seems that sneak preview may cost us. VentureBeat’s usually-reliable Jeff Grubb just dropped his first episode of The Game Mess Show, in which he plans to provide regular behind-the-scenes updates on upcoming game events and announcements.

I'm less certain [about an Elden Ring reveal in March], and I'm less certain because I think that the leak might have messed things up a little bit.
