One book is written by the guy who invented the character of Jon and gave this interview saying he planned to write a lot about Jon in his book, Action Comics.
The other Superman title right now is the book simply called Superman. Here are the June solicitations for that title that went out to retailers (Two separate #1s, but both by the writing team assigned to the Superman title):
Superman Rebirth #1: "The world needs a Man of Steel, but can Superman protect the world while raising a super-son with his wife, Lois Lane?
IT BEGINS: Now it’s Clark’s turn to be Pa Kent and teach his son what it means to be super, but who is hunting Superman’s son—and why?"
Superman #1: "The Last Son of Krypton must decide whether to help his young son use his new and rapidly increasing abilities, or hide them from the world.
THE CREATORS: The team supreme that brought fans the adventures of Damian Wayne in 'Batman and Robin' returns for the adventures of Superman and his offspring."
So, you've got on the one hand the book written by the guy who invented the character of Jon, has been writing a lot of Jon in Lois and Clark, and explicitly promises a lot of Jon in his series, and then on the other hand there's the book written by the people who brought you the adventuries of Damian Wayne, where the summaries for the first two issues are both all about Jon.
This whole freaking Superman line is now about Wesley Crusher. I mean, Jon.
They're using Superman name to push people into liking a new 10-year old superhero, and killing off the existing Superman in the process, replacing him with a Superman who was outdated and had run his course five years ago and had lower sales, purely to allow them to set up Super-Jon, and offering not a crumb for anyone attached to the new52 universe's real Superman or who doesn't want to read about kids fighting crime after math class.
I had the same idea as you did, that maybe there'd be a book where Jon wasn't really involved, or even a new52 Superman book, but those hopes got crushed as information slowly dribbled out. I mean, it's obvious that that book doesn't exist.
