Warner Bros. recently announced their slate of ten Justice League movies, which apparently didn't impress James Gunn all that much.
Regarding Guardians of the Galaxy and Man of Steel, Gunn's Guardians currently has netted about $769 million worldwide to Man of Steel's $668 million.
Disney was also confident enough in Guardians of the Galaxy in that they announced a sequel even before the movie premiered.
Warner Bros., meanwhile, added Batman and the Justice League characters to the Man of Steel "sequel."
Sorry DC fanboys: James Gunn +1; DC Movies 0.
