Trying to find info on their packaging story. Last I heard the official tooling seemed to be moving off systemjs+jspm in favour of WebPack, but I don't see any clear info on this; does anyone know?

We've started experimenting with systemjs and really like it (though support is a bit limited right now, plus it not really liking PhantomJS/karma), and we want to modernize our Angular 1.x app packaging/loading/bundling, but don't really want to do needless work if we have to move to another solution for Angular 2.x.
