I think port over capability will be more limited than you think. Even though it is still CFS3 under all of it, a lot has been redone, some features repurposed, etc. I think it is more than just business sense in making it that way. As I have been considering building a new freeware expansion, in order to bring the quality of each bit of content up to the max, a huge amount of customization and standardization is required. If you want the level of polish WOFF has achieved, especially with how much code they've reworked, it has to go through some sort of official filter to ensure it has all the same features that the rest of their content has. There are still third party mods for WOFF, but as far as I know, aircraft, and possibly some other items aren't possible without going through official channels.
Still, that is a bit different from the open nature of our community here. I'm hopeful that things will develop in a way that benefits everyone. And for what it's worth, I'm pretty stoked that a WOFF style campaign will be coming to WWII. It's something I've wanted forever. Also, I think this will wipe out many of the limitations we've been dealing with for years.
