Angular 2 coming out isn't going to make Angular 1 disappear. It might not even end first party support for some time, though the fact that Angular is open source means that there are options for maintenance even when first party support does end.
You might choose to switch to Angular 2 later just as you might switch to anything else based on a future cost-benefit analysis, but you don't have to.
> So, it would seem that Google is heavily invested in the current version and will need to support it for a while. In a Q&A session at ngEurope Brad Green said that you can expect at least 1.5 - 2 years of support for Angular 1.3 after the RTM of Angular 2.0 becomes available
If I am working on a long term project choosing a technology that will be supported for 1.5-2 years, would make me feel uneasy.
But let's just pretend that the 1.x codebase will be so stable that it won't need support. What about the third party libraries that my project will depend on? Should I expect all of those to be maintained after Angular 2 is released?
For real projects these are deal breakers. Recommending Angular for any serious project that is expected to be used for years is irresponsible.
