No one knows for certain. I personally believe that, yes, we will get a Sly 5 eventually. Sony still believes in the IP, otherwise there is no way we would be getting a movie.

I would say that the best way to ensure the fifth (sixth, technically; seventh, even more technically) game is to go see the movie in theaters and get your friends to see it with you.
