It's no surprise that the followup to 52 will be called Countdown. This looks at the post-52, post-WWIII DC Universe, with the signature character of Jimmy Olsen.
It's a little surprising that the Legion will have some contact with Countdown. We've already seen a Legion flight ring in the promotional material, for one thing.
What's a lot surprising is that a Legionnaire is in the new promo poster. The poster (which is on the cover of this month's Previews and will be offered for retail sale later) has Karate Kid - again - shown running with the pack, at center left next to Hal Jordan's right hand. Unless, of course, they're going to pull the same thing here that they did with JLA #1 a few months ago, and just put him on the cover as a red herring.
But what's even more surprising is how they describe Jimmy Olsen, via Wizard Universe:
I’d say our everyman character in the story is Jimmy Olsen, who to a great degree fits that bill within the DC Universe anyway. He has links to the Justice League, the Legion of Super-Heroes and the New Gods. And he is in the unique role of being not only a traveler through the mainstream DC Universe, but also becomes increasingly aware that he might have a bigger part to play in all this than he’s ever suspected.
This Jimmy has a link to the Legion?

Wizard Universe has an interview with Paul Dini, who'll be the main writer on the project. Meanwhile, Newsarama has an interview with DC Senior VP-Executive Editor Dan Didio and Senior Editor Mike Marts (who’ll be editing Countdown as well as the regular Legion book). Dan DiDio remarks on the Jimmy Olsen storyline:
One of the key storylines follows Jimmy Olsen throughout the DC Universe, and touched upon a lot of what our long-time fans will remember Jimmy to be with the character from the’60s and into the ‘70s – again, while keeping it fresh and contemporary for a modern audience...
This is being called "the book where shit blows up."
