I doubt it. It's not like IE8 is dropped by Angular. If you want to use Angular with IE8, use v1.2.
Dropping IE8 support + the "don't worry, it's free" Dart port make me very concerned about committing to Angular for anything I might be maintaining 2 to 5 years from now.
Anecdotally, I've noticed more established/larger tech companies (other than Google) using Ember, and more startups using Angular (with some exceptions like Amazon, which uses Angular). I think this is also a reason.

Right, that's the problem.
