[HTML5] Plans for HTML5/WebGL?

Hi everyone! I want to re-open this post. Maybe there are more options now with HTML5. We are developing a project with UE4 to package in HTML5. we are working with source code and Emscripten with success, we can do the package to HTML5 (it can run in Firefox only). But now, I have some questions: When could we see a release with HTML5 operative? When can we see our HTML5 projects run in all browsers? Now, have you got some Unreal dev-version with more options for this platform? It’s possible to work with this? Do we need some custom license to have access? Thanks!!
