Doubt anything will change in ember to accommodate any specific transpiler , or (transcompiler) if you would. Do have a look at https://code.visualstudio.com/, ember is used in that first example, so using specific tools for better integration will be a better option at this stage.

Actually typescript already works fine in Atom, which this light weight Visual Studio is based on.

I already got Atom-TypeScript working fine, but I am having issues with ember-cli-typescript not working, I was hoping for an official way of working with it.
