Yeah...I'm thinking the "big push" for Teen Jon came to an end after his second cancelled series in under 5 years. They put everything they could into building up SOKE as being the main Superman title with Teen Jon as it's lead...and it still ended up being overshadowed by his dad in Action. And now Clark's back as the main Superman with a new book...and Teen Jon's been demoted to extra in what is essentially a team book.
