I also think that in 1 or 2 years...pure guess as to the time based on forum speculation....that OFP2 will come out. This is probably the most interesting sequel set for a game I have came across.
Basically put, the two main developers of OFP 1 split after they made the game, but they both wanted to produce a sequel.
Codemasters, who has the rights to the OFP name, is currently producing Operation Flashpoint 2: Dragon Rising, for release in a few years.
Bohemia Interactive, the other developer, is working on the Armed Assault (ArmA) series which basically seems to be like the FSX scenario in the FS world. Much OFP classic code, rehashed with updated graphics. Same basic gameplay though.
As for what OFP2 will be like...I have no idea!
Esselbach,
For addons, simply make sure that you have the original OFP game, along with the Resistance expansion pack, and that the game is patched to at least version 1.91. Then, after downloading an addon, put the ".pbo" file in your OFP/Res/Addons folder and your set!
