Reading the blog post today that has already happened. Ashley says they are going to write a new runtime so I wouldn't expect any more support for C2 and like Construct Classic it was a great engine that was improperly advertised as an engine for professional game design.
I would hope Scirra puts C2 in public domain and let the people that designed all the plugins work it over and it would probably be a great engine but I doubt that will happen.
I know, I'm just saying this doesn't apply to me, hence why I would be moving away from C2.
The Construct 2 runtime in the Construct 2 editor (C2): this will see continued maintenance much as we have done for Construct 2 over the past year.
Doesn't look like they plan to dump it anytime soon. I'm just saying when they inevitably do dump it (hopefully) years down the road, that's the end of that.
Ashley Sorry if I'm coming across as a killjoy, I just am highly skeptical of anything that hasn't proven itself to me yet and I did say I would buy into the subscription model if there are extraordinary circumstances, which you've done many times with C2.
