Yah the Superface card is old, but the thing is, before the Attitude era, it was how the WWF buttered their bread. Cena's been doing it for about five years, but Hogan did it for 10 years plus. Warrior did it during his run as well. It's a proven money maker for the E and as a huge part of their viewership is composed of children, many of those children's parents will buy them their favorite superstar's merchandise. The thing is, during the Attitude Era, the average age of the WWE viewer was from 18-34, but not many of them would spend their disposable income on WWF merchandise. They'd buy PPVs, but not tshirts and the whatnot. Now that those viewers have gone away but the same core of children really hasn't, the merchandise sales haven't really slowed if at all because the source for their merchandise sales, the children's parents, haven't left in the droves that the older viewers have. So it will probably stay that way until the merchandise profits start to shrivel in the way the viewership has, and honestly it hasn't terribly. Raw is still the top rated cable program and still perform fairly well on PPV, they still make mad cash off of advertising so until the bottom totally falls out, which won't happen until competition truly emerges, then I doubt the Superface characters fade out.
