Civil War Announced by Marvel for Summer 2015

Civil War Again for the Heroes of Marvel Comics?

According to a new article from ComicBookResources.com, Marvel has teased a return to the popular Civil War story line. There are literally no other details than this image of Iron Man and Captain America playing tug-of-war with Spider-Man in his Iron Spider costume. The image was rendered by Adi Granov with the familiar cover treatment from the original 2006-2007 crossover event. The event was widely popular, even spawning a variation of the story for the multi-player, button-masher video game, Marvel Ultimate Alliance 2. There has been wild and unfounded speculation that Civil War might be the foundation of a future Avengers movie. But as many of us know, this would be a very different version of Civil War with so many of Marvel's movie rights held by other studios.

What is Marvel thinking here? And what are your thoughts on all these revisits to earlier events from Marvel History?
