They have been their ages, for as long as I can remember. When you could modify files to get lots of stuff during the closed beta, I deeply explored all of those (Items_Server.zip, Weapons_Server.zip, Water_Server.zip, Vehicals_Server.zip etc etc) and found numerous files. Its highly doubtable that they will be implimented. The whole files for how they should act etc aren't even done properly, let alone any graphics files. All that is there is a template, just incase they do add it. I doubt they are actual upcomming things due to the facts that they still use the Battlefield 2 file editor and therefore these templates are just something their by default.
