Takeing a mod from an old game and putting it on a new one

[b2bomber]

OK so I have a question if emergency 2012 where to have a similar file structure to emergency 4 (mod wise) what would be have to be changed if you where to have built a mod for em4 but wanted to put it on 2012 . I know probably there would be a new file extension for prototype files. I am also pretty sure the UI and Unit, and specs XML and all the stuff to go with them would change but what else? I guess I am asking how hard would it be? or is it just more of I time consuming task?

thanks,

Dont you think this is question best suited for asking AFTER the game is release? Until then I suspect no one knows but the devs.I mean we may be able to find out that the scripts still use C++, but unless we know exactly how the code for EM5 is written theres no way to tell.
