I think you're right. Probably something similar to how they changed Java from the 1.x to the 5, 6, 7... series. It did take a couple years for people to stop saying 1.5 though, as I suspect will be the case for people saying "Angular2" trying to find a way to distance themselves from Angular 1 but not really caring if some component was written for 4, 5, etc..

you'll find that generally, we refer to it as "Angular" or "Angular 4.0" - officially, AngularJS is 1.x.

We'll see how it shakes out, but so far our community has been pretty awesome about it.
