I'm sure this is something that most of us are hoping for. My guess would be that they aren't answering here because they are saving the reveal for a future blog post.
Burvey you might be right about that. They are probably saving this up for a future reveal. I hope so
I feel like maybe its too obvious a question... The Scirra devs are probably thinking "Of course we are going to provide that, just sit back and wait for us to announce things in our own time and stop trying to pre-empt all our good news!".
I mean it seems really unlikely that official plugins for iAPs and ads would get upgraded and become officially maintained by Scirra while plugins for connecting to GameCentre and GooglePlay Services would be left to third party solutions.
If Scirra maintain plugins for GooglePlay, GameCentre, maybe Steam?, maybe WinPhone?, iAPs, some different ad networks, that would easily be worth the annual subscription price imo.
I think its likely this will happen, because that seemed to be the original vision for C2. C2 has official plugins for those things, its just that in recent times they weren't maintained and users came to rely on third party options that worked better, I guess because Scirra was prioritizing their time and energy on building C3.
I must admit I was one of the people who was all in an uproar about a subscription payment model. But the Scirra blog post about the new mobile app build system, and updated iAP/ad plugins sounds super awesome! Ill be purchasing C3 as soon as its available.
