Recently Bleeding Cool posted a report claiming that Captain Marvel (despite poor comicbook sales) will not be cancelled because of all the strong support. They also claim that Captain Marvel as Carol Danvers will be appearing in Avengers: Age Of Ultron, which would of course boost the sales of the comic book. There were rumors of Marvel planning to include a cameo for the character, but decided against it without the proper character set-up. Take this with a grain of salt, but we will hopefully get more info about it soon.
