GameSurge has posted a Q&A with Raven Software's Brian Raffel, talking to him about their nearly-complete action title, Soldier of Fortune. While brief, Brian does talk a little about the possibility of a sequel, as shown in this excerpt:

If Soldier does as well as I think we will have a mission pack and a sequel. I have already taken steps to secure John Mullins (our mercenary) for the sequel and this time I want the all the missions to be based off of real scenarios that the military have had to do. I would also like to add more gore zones like affecting the hands and feet as well as more unique animations. If we have time I would like to implement our skeletal system so we can fit more animations in general.
