Angular2 or your solution?

Question

Angular

JEE (Spring) is used as a back-end, front-end is designed for devices with mandatory JS support (there is a separate version for the rest), so jsp and the like will only interfere. The calculation is done on RestFul, and therefore AngularJS was chosen for the client side, but soon with the release of Angular2 it became interesting:
+ how long will the first version last?
+ what kind of miracle is Angular2? well, it doesn’t look like the first one at all, and where is the client angular ( from here ), where only the mass is connected, it’s not clear what lib, and then they provoke some errors?
