To put some perspective on the Flash/HTML5 thing (mostly for Vicu, but some of you might might enough this), Flash and HTML5 are not equivalent platforms. HTML5 isn't a 'thing' or discrete entity like Flash is. HTML5 standards for browsers just bring together a combination of features (Canvas element, faster javascript) that allow for flash like features.
To say HTML5 can go down the same dark path flash did in the realm of performance and bloat is sorta a silly misunderstanding. It would be like someone saying "Oh well C++ has gotten so bloated over the years". Adobe makes a product and authoring tools for that product. They expand it and they add new features to their authoring tool that makes the fast majority of Flash content.
HTML5 is just a bunch of tools. No one is controlling javascript. You have unlimited potential there, you just need implementation. Flash's advantage currently is it has a well developed authoring tool. HTML5, just being a collection of standards and a real programming language is something that is, at this point, potential Construct has the benefit of being one of the first tools help make HTML5 content, especially for games. That's both big for Scirra and great for developers. Flash WILL die. Even adobe knows this, which is why Adobe Flash Professional has HTML5 export abilities (or at least some sort of converter, I don't remember). Even if their platform dies, they can still monetize their tool. It's hard to compete with an open standard that has many advantages and very few drawbacks, it's just a matter of time. When enough folks in the content creation market are skiled in HTML5 and it's deployment and when things become more cost effective, things will change. HTML5 will only improve as content creation tools are made to support it and as browsers improve performance.
Flash still has some advantages now. They come in discrete, independent files which can be used as standalone executables, for example. You know things will behave the same on any platform. But since html5 is a very open standard, as soon as someone comes up with a good way to package something made in html5 as a single, easily embedded, clean entity, it'll happen. People will want this to make it easier to upload games to places like kongregate easily and more securely. But if I were to guess, I'd say there are probably ways to do it right now. The question is more about which implementations will end up being the most popular and well supported.
So while Flash and HTML5 cover a lot of similar functionality they are very much NOT analogous platforms and there is little reason to expect them to share similar histories. HTML5 is a specification, flash is NOT. Flash has a single vendor, HTML5 either has no vendor or many vendors depending on how you look at it. It would be like saying HTML4 and PDF are similar "Things" with similar histories.
But anyways, I hate webgames! So whats the vague timeline for exe-export? If it's anywhere within the next year I'll be thrilled.
