Speaking to the USA Today, exec Frank O'Connor, overlord of all things Halo, has said that the franchise is mapped out until 2015.

"We do have a plan that goes out at least six years," the chief says.

"Eventually, it will become very apparent that there is a plan for the way the canon all ties together and the way the comic books and the novels all tie together."

Beyond games, Microsoft are also planning movies, comics, book and even toys. More Halo soon.
