I don't know. I see that some veterans have made some strong arguments that C2 is lacking in its ability to export, and while that's true, I don't think C2 ever promised this. I was promised a capable, fast, and easy HTML5 game engine that would make rapid prototyping possible, or ease the process of creating HTML5 games or simple multi-platform games. The fact that the games can export (albeit non-natively) to so many platforms is impressive, but it's a bonus feature for me.
There are other options for those who want to have their cake and eat it too. I'm sticking with C2 for the foreseeable future because it's in line with my goals and needs. I have every confidence that exports will get better and features will frequently be added because that has been my experience since I picked C2 up just a few months ago.
