Unfortunately, we're not allowed to publish roadmaps or speculate on such information in public venues like this. I can put you in touch with one of our project managers, if you would like; we are interested in learning about commercial and enterprise use of the product. I'm assuming the email address you're using for this forum is appropriate for contact? Let me know.
Aahedi -- it is our intent to keep the app moving forward. What sort of apps are you building? Are you building apps for personal use or for a company? Also, our projects are compatible with standard Cordova CLI (we build Cordova apps) so it is very easy to switch to using Cordova CLI if, for some reason, the XDK no longer served your purposes.
To build it locally you should use Cordova CLI 5.4.1 or 6.0.0 and then make sure you add the cordova pluggable webview to your project. See this article > https://crosswalk-project.org/documentation/cordova/cordova_4.html and this > https://github.com/crosswalk-project/cordova-plugin-crosswalk-webview
I am evaluating XDK at the moment to build an in-house app.
I do feel a bit cheated but that is the problem using frameworks you are a slave to their roadmap, which is never published :-)
