Create Ionic 4 app from Angular 6 project

I have read some news about Ionic 4 and that it will be using more features of Angular (like the router). Does that mean that the project structure of a Ionic 4 app will be even more similar to an Angular 6 project?

Will it be possible to generate a Ionic 4 project out of Angular 6? This might be a very useful feature for the CLI.
