I'd be willing to bet that AngularJS will be hugely successful, and will gain a significant share of the Single-Page-App market.
I'm not saying Angular/Flex is the same beast. I'm saying that one of market segments that is going to find it most useful is the same people who were looking at Flex to solve problems back in 2006/07. Naturally, technology has progressed quite a bit since Flex came out. For a JS library, Angular hits a pretty good sweet spot for those same large dev teams looking to build native browser-based apps.
By contrast, AngularJs is not being sold into the enterprise by anyone (yet?), and is, IMO, better at solving those problems.
Hence my prediction: unlike Flex, AngularJS will gain market share in single-page-apps outside the firewall, as well as inside the firewall.
Disclaimer: I worked with them implementing that.
