I've heard the New Gods theory before, and it makes sense. Not the first time (and certainly not the last time) that publishers fucked with a creator's plan.
On that line of thought. My Peter David WTF list:
Marvel wanted Hulk to be Savage again. David wanted to make the title into a suspense type book. Marvel removed him from Hulk after 12 years and the resulting Savage Hulk stories lead to the titles' cancellation after about 6 months.

Young Justice is cancelled to turn it into a carbon copy of every other team/Johns book out there. The reason was that they wanted to match it more to the new animated series.

Bow ties are coool.
