1. The New Goal
While going into this, Geoff Johns(Creative Director for DC Comics) describes this movement as something to get back to the core of the characters. The goal for the writers under DC is to bring back what we loved most about our Superheroes. From Superman being the symbol of Hope to Green Lantern conquering fear, we'll see the old mixed with the new.
2. The Best Talent
With their new goal in mind, DC has begun pulling in the best writers and artist from DC's Past to help write these stories. Writers such as Greg Rucka, Scott Snyder, Dan Abnett, and Tom King and artists such as Robson Rocha and Otto Schmidt. If their intent is quality, this is a good start.
Now you're probably wondering: With so much effort being put in the story: What could change in the DC universe that could be noticeable.
