i think we can all agree with C2 having the best way of managing events, but the truth is that it doesnt export native and that is a problem, there is nothing that can make html5 look better than native, i see html5 as just another platform to export, not the "MAIN" platform, engines like unity and GM already export native and html5.
There is only one reason that prevents Scirra from going native on C2. Ehemmm! "MONEY".
It takes a lot of money because it takes a bigger team to make native exporters.
Top 3 features that is mostly requested for C3:
1) Native Export - Denied
2) 3D - Denied
3) Improved Plugin Support - Accepted
Atleast the 3rd one is accepted by Ashley.
