I wont argue that we're headed in that direction, but it's sort of like a cross-country road trip; we might be headed that way, but we've got a whole lot of road to cover before we get to that end point.
Sure, when it comes to the comics DC doesnt have a clue, and hasn't for damn near thirty years (a few highlights notwithstanding). But despite this, despite the lackluster world-building Superman has suffered from since the late 90's and all the flatline quality, the Super-titles still sell decently, holding solid mid-range showings when they're not higher up the rankings. Superman still holds down multiple titles, where a lot of major names still cant. At his worst, Clark still had two titles, and recently he had, what, five? Seven, if we include mini's?
Even though he hasn't had a cartoon in twenty years and doesnt have the larger-media showings that properties like Spider-Man, Batman, and the Avengers get, Superman is still the fourth highest grossing comic book property on earth. That's a whole lot of money (277 million) for very little work.
Yeah, Superman's on a downward spiral and has been for many years now. But he's still a long way from hitting the bottom like Zorro, Tarzan, and the Phantom have. There's still time to course-correct and return the character to his rightful, lofty place. And indeed, to most people he's still there and never actually left. Its just us few who read comics who can see where the franchise is headed.
