What attracted me (well, the company I used to work for) to C2 in the first place was it's ability to build games for Ouya and quickly export to android & windows platforms for testing. This simply isn't a feature i've come across in any other game engine.
Personally, what I would want as an evolution to the Construct family is being able to package and export an APK from within C3, maybe even sign it too so it's ready to go instead of having to mess around with .BAT files to generate keys and run files through CocoonJS. For creating a desktop game, why not have a 'wizard' creator where you can select splash screens and game icon before compiling too and the backend does all the hard work?
Anyway, my point is that 10 years ago games design, creation and publishing was prohibitively expensive and difficult. If Construct is aiming to be the "games engine for everyone" then the focus should be on making it as easy as possible to get your content out there to as many people as possible.
