That was the basic problem with the '90s implosion. There were comics featuring some specific new characters, or new series, or comics from new publishers that suddenly were worth a lot of money, and then speculators jumped on the first appearance of any new character or series, thinking that there would be value there too. For the value to stick, the interest has to stick, and that's only going to happen under certain circumstances. I haven't been reading the DC stuff, but from what I can gather it seems too wild to maintain steam, since you can't maintain the level of insanity that the storyline is pumping out
