A quick lesson in business economics
1). Codemasters own the Copyright to the Sensible name and to all their games.
2). They also own all the source code, graphics and sound to all versions of all Sensible games.
3). SWOS was a big money spinner, and there is no way on this planet that Codemasters would let SWOS not get further releases, after all, there is no point buying all that stuff if Cannon Fodder is the only release!
I would bet my life, you will see SWOS again on other formats.
