I just downloaded the 3.0 alpha and it was mind-blowing, with the most interesting parts being the EventDispatcher and the KeyboardEvent.
I just want to ask, is there a planned support for game controllers? Most people these days use their PS3 and/or XBOX 360 game controllers to place PC games and this is starting to be a trend (google Steam Machines). It would be nice if cocos2d-x had innate support for game controllers (PS3, XBOX, as well as USB game controllers). This will probably make development for PC much more plausible using cocos2d-x.
