New JavaScript framework from former Angular developers (aurelia.io)

Dammit.

I declared an internal (as in, in my head) and indefinite freeze on learning any new Javascript frameworks since the Angular2 flap.

But this looks kind of interesting...

The website is beautiful.

Please provide a comparison table with the other MV* frameworks, or a video that isn't 27 minutes long, so I can get a quick overview.

There was a great interview with Rob Eisenberg about Aurelia on the dotnetrocks podcast recently - http://www.dotnetrocks.com/default.aspx?showNum=1097

I am concerned with testability?

Will protractor still be used?
