There's no reason to be a dick. Sarcasm is one thing. An over abundance of it is something else. You're not winning any friends here by such posts, and to be constantly hounding someone about headliners, when it's clear that he's not ready to say who it is does not sit well with us, and we're explaining why. Glenn carries a certain amount of respect here for all he does. You're probably new to the PP community, so you may not know how it all works, but when he's ready to tell us, he will, and we respect him enough in his ability to produce to not dog him once a week until we get our way, because we KNOW he delivers.
Sit back and let the man work. It's not like headliners won't be happening, but you need to learn to take the typical American additude of "NOW NOW NOW NOW INSTANT GRATIFICATION OR HATE FOR ALL TIME NOW NOW SPOILED CHILD" and not apply it here, or people are bound to not like you.
