The Obsorne Effect
The Angular team faces a problem. How do you talk the great new features of Angular 2.0 under development without damaging use of the current 1.x? This effect is often called the Obsborne effect, named after a 1980s computer company whose marketing contributed to putting the company out of business. In short, the better 2.0 sounds, the less people will want to start or continue projects built with 1.x.
