Generals will use the same file format for 3D models as Renegade (W3D). But Westwood still hasn't released the 3ds to W3D converter they would release for Renegade. So we still can't edit them. I can tell you that Generals is moddable: but 200,000 lines of ini-like text is a bit too much :S Editing without a program will become impossible I think (then again, the TibEd 1.x engine can't handle the Generals file formats... Incoming: TibEd 2.x, which was originally designed for Emperor... but I was slightly delayed :O).
