Hi Dave,
That's not about Electron Apps. ... It's about the browser engine. I think, they'll still call it Edge and it will look the same but the internals will be different.
Chromium it the open source version of Chrome browser. The browser itself consists of several elements.
2 important are: The rendering-engine and the javascript-engine
At the moment
MS uses: EdgeHTML for rendering and Chakra as the js-engine
Chromium uses: Blink for rendering and V8 as js-engine
Firefox uses: Gecko Quantum for rendering and SpiderMonkey as the js-engine
I think it's clear, that they will drop EdgeHTML. I'm not so sure, if they also drop Chakra. ... BUT we'll see.
