Gameplayer has an exclusive interview with John Doyle, the producer of Need for Speed ProStreet. The article goes in-depth on the new direction the series has taken and how that will affect the brand for fans of the series.
"The difference is that we've focused in on your performance, rather than the open world and cops. I think this will be a welcome change of direction for the franchise and is an area we'll continue to explore. However, I don't think that means you've seen the last of the cops in Need for Speed."
