This is cool, I just hope they balance it with Supergirl. They spent a effort to ensure that Superman didn't over shadow her and also Supergirl didn't overshadow him.
She proved she could protect National City, but due to Superman's absence for his child's birth, he handed her the reigns of protecting Earth.
Not to mention Supergirl just had Lex Luthor and has featured previous Superman foes, I imagine some rehashing of history.
Another fear, they somehow make Superman seem like he's new on the job.
