I'd like an F-16C but I doubt ED will do one knowing that people are going to compare it to a certain free mod in another sim until they have all the features in place to be able to compete with it on an even footing (they'd just be drawing attention to features of the other sim that they don't have yet). Until AG radar, new FLIR and dynamic campaigns are implemented in the game I doubt ED will put much thought into an F-16 module and frankly I'd consider those features more important than the actual module anyway, especially since they can apply to other aircraft or the sim as a whole.
Don't get me wrong, if ED released and F-16 module today I'd buy it anyway, but since I only play single player I'd be asking why I'm spending money (because I would be spending the money) on a product I can get better elsewhere and for free. Put simply, I doubt ED wants to release a substandard module especially when they can focus their efforts in more productive areas; I think they are making the smarter move here.
