It's interesting that its:
... an updated framework that is still fully backwards compatible with existing React-based applications.
So it sounds like a drop-in replacement for the previous incarnation which is now even more "responsive"!
This looks really great. New APIs but old ones mostly work is a good thing. Definitely not like the Angular 1 to Angular 2
Have they mentioned anything about timeline? My guess is 6 months out!
That's an interesting progression: it's 99% ready and then they decide to start making it less ready...
Two steps forward one step back.(because opposites, react... rimshot)
