No More Bourne

If you're a fan of the Jason Bourne movies with Matt Damon, the newest film could be the last one. Or at least the last one starring Matt Damon.

There is a 4th and 5th book so there is material to work with, but Damon is unsure if he wants to continue in the roll.

Could Bourne be like a James Bond and continue regardless of the actor? I think he could and I'm guessing they'll keep making the movies as long as they keep making money.
