Sadly, I agree with the overall sentiment here. This isn't a complaint about the subscription model per se - it's just saying that C3's feature set isn't very exciting yet, at least for many of us. It will do all the things C2 does even better (and cross-platform, though that probably isn't useful for most current users), and that's about it.
I'd love to know what else to look forward to. For example, are an improved debugger and better modularity/project organization features are planned at all, and when we can expect the editor SDK? The excellent idea of a Flash/Godot-style properties animator with timeline has come up - is that a pipe dream? If so, maybe that's fine, because there are enough other great things coming we won't even miss it. But right now, based on the C3 announcements I have to conclude we probably won't see major features for quite some time. I would like nothing more than to be proven wrong about this.
In the meantime I'm looking forward to the beta tomorrow. I hope it goes well.
