The only thing i know is what i have read, which no doubt is the same as you, but i've seen such to know better.They creep, they crawl, and then BAM, they are in and they are the norm.
What i see happenning, which the "Wildstorm" universe has not been addressed yet, is the complete removal of everything DC has gone through to rebuild itself, in the past few years. "52" is down the drain. Most especially, the "Golden Agae" Superman is now no more, as is the Justice Society. I'm surprised that there are not more people upset about that.
Everything that is "old" has been wiped out. Kal-L, Lois Lane, Earth-2, The Daily Star, everything...GONE!
Don't worry, the public domain or the heirs will be rescuing Superman from the talentless, evil hands of DC comics soon. I hope.
