Superman is getting new threads (presumably the black costume we saw him wearing on the last page of Action Comics #0.) There'll also be a musical chairs of Super suits so to speak with Superboy soon getting to wear the Kryptonian armor and Superman temporarily going back to his jeans, T-shirt, boots and cape look from the "5 years ago."
