Basically, DC Comics became DC Entertainment. Publisher Paul Levitz retired when WB brought Diane Nelson in as executive of the new entity, answering to the president of TW. Time/Warner is just, finally, fully integrating DC Comics into the company, allowing easier access to their stable of characters for film, tv, books, video games, animation and electronic content. Time Warner is embracing DC, instead of being embarassed by them. And Diane Nelson will act as the bridge between the Comics side and the other entertainment sections of the company, so that, perhaps, they might actually make another Superman film, or Wonder Woman, Green Lantern, etc, without many hassles and clearances.

Time will tell if this affects the comics side of things, but it should make it easier for cross-platform access to a wider range of film/tv, etc.
