You know, at some point, the JMS's and Devin Graysons of the world are going to retcon and, bascially, fanfic these characters so much that no one wants to read about them.
They'll be too "mature" for young readers. They'll be too "sophmoric" for most adults.
And, basically, the ever shrinking cadre of adults who obsessively collect the characters will die out.
Eventually, interest in these hopelessly effed up, schizophrenic former icons will be so low that you can't even get a syndicated TV adaption out of them.
