I've read an interview about Jagged Alliance 3 in a Russian mag. It looks pretty promising, although there's not a whole lot of info available. Yet. Here is the most important stuff:
- There will be 4 factions
- The game will have missions, no conquering/defending areas
- Some old mercs will be back
- An improved version of the Silent Storm engine will be used
- The team consists of Nival (Silent Storm), G5 (a small studio IMO, have made some crappy games) and Akella (Pirates of the Caribbean) members
- Currently the game looks like a mix of Fallout and Jagged Alliance 2
- Some maps are ready and everything looks cool when it blows up
- The game will take place in South America
