To be honest, it's concerning. Once I've finished the current project I'm working on, I'm planning to do another one that targets consoles.
But choosing Construct 3 without knowing if exporting on consoles will be available once the project is finished is problematic.
Now, I don't doubt the efficiency of Chowdren matpow2. It seems to be a really cool piece of software and I'm strongly considering it. But the problem is that third party are unreliable by nature. What if the company folds? Or is unavailable for various reasons like it's the case for NotionGames? (being overworked, focusing on their own games, too many projects etc etc)
I don't suggest Scirra should develop an in-house export option. It's too much work. But having a clear list of third parties companies, or an official partnership with Chowdren, or some kind of a clear pipeline for console export would help reassure developers.
Nobody want to create a game only to get stuck with something unusable after all that hard work.
And if Construct 3 wants to really solidify as a true professional engine in the long run, that's something they should address somehow.
