More Planets?

Astronomers have published a study of stars in our galaxy that indicates most stars are single, that is, they do not have a companion star. Previously, scientists believed that most of the Milky Way's stars were in fact binary star systems. I seems like this would mean that there may be more planetary systems in the galaxy than would be possible if most of the stars were part of binary systems. I expect that planet formation is less complicated in a single star system. Looks like we may have to modify a few parameters in the Drake Equation.
