Yeah, most people will be totally "Who?" But I suspected there was a reason they were reprinting TALES OF THE GREEN LANTERN CORPS a couple months back. Really, for people who know old-school GL, there's no one else who could be behind this.
That said, I'm still waiting for the mind-blowing twist that'll rival the first issue of SINESTRO CORPS. Black Hand, Nekron, zombie Earth-2 Superman... who else? Who's gonna be the surprise pants-shittingly-shocking character?
