How effective is AngularJS 2.0? What all (facts) can we expect?

(PLEASE DON'T QUOTE OPINIONS. JUST FACTS AS ACCEPTED BY THE WHOLE COMMUNITY.) (Opinion-based quotes are not legal on this site.)

Now that Angular 2 is in Release Candidate 1 (RC1);

I want to start a thread on what all claims were made, & how much has been deliverd/will be delivered. What all was aimed & what has been done/will be hopefully done.

I am asking from a programmer's or engineer's perspective. It is a question related to programming.

Please only quote the most authoritative, & verifiable facts. Specially relevant to engineering, programming, new web standards, & tech.

I want this to be an authoritative thread. Request only the most, most experienced people to speak. Requesting an Angular-God's zone.
