Well, both JoWooD and Nival said they would like to do Silent Storm 2 some time ago. At present though, they have more than enough other stuff on their minds :). With Nightwatch (using a modified S3 engine I believe), Heroes of Might and Magic 5 and the other games they do, it will not happen just yet. Maybe after the English version of Nightwatch hit the streets.
There is also the mod for S2, Hammer & Sickle, that is now turning into a game. Can't remember when it's to hit the streets, but it's getting closer.
Anyway, enjoy S3! I haven't gone through it myself yet because I'm very pressed for time these days. It's as hard as it's good! We'll hear it soon enough if Nival decides to do Silent Storm 2.
How's things in RL? Good to have the comments up again here!
