We possibly did announce C3 too soon. Our intent was to
a) start raising awareness of a new product coming out at some point in the future, and
b) explain why Construct 2 development might be slowing down somewhat.
However for the reasons I posted earlier we never felt like it was a good idea to announce anything further. So I can see the frustration. But I'm not sure what else we could do, other than e.g. announce something we're still not 100% sure will launch, and then distract sales away from C2 for something which doesn't even have a release date yet.
We have actually been working on further hiring and are still looking in to some expansion - we just haven't made announcements yet. But Scirra has been bigger than just Tom and I for a while now.
