Slashfilm says:

Today at Disney’s CinemaCon presentation, the studio announced that beginning in 2015 we’ll see a new Star Wars movie every summer. The plan is to begin with Episode VII, written by Michael Arndt and directed by JJ Abrams, then alternate between standalone “spin-off” movies and new Episodes in the core storyline.

You see, if we cut the goose wide open and take a look at its intestines, we'll be able to figure out how it lays those golden eggs. Then we'll all have more golden eggs! It's what we like to call a win-win situation.
