Can AngularJS Maintain Its Dominance?

As an Angular user these changes concern me greatly. Not just the scope of the changes (which is huge) but the timeframe as well.

What really worries me is that with version 2 still some time away the scale of the changes will frighten people from using Angular until they see where the dust settles. The problem with that is you can't just put work on hold until the next version is released and so by the time Angular 2.0 comes out, no matter how good it is, it could be a lame duck since most developers have switched to Ember or React or what ever the next cool framework turns out to be.
