Don't follow the comics much. I'm aware there has been a month's long story where Superman was off planet. Originally it was teased as Superman would not make it back. nut wonder of wonder he will do so. I saw a preview and it seems that arc is ending with Clark coming back to Earth. Will he be retired as Superman once he returns given Jon is the new Superman? Renaming Son of Superman back to Superman featuring Jon with Action featuring Kal-El?
