Still waiting
The good think Luke Cage has going for him is that he has a cinematic and dramatic origin. Alot of intresting stuff happens before he even gets his powers.
I would be surprised if we don't see the character in the upcoming SHIELD tv show. For-profit prisons experimenting on the incarcerated with variations on the super-soldier formula fits perfectly in a post-Avengers world. And if the character (and the actor playing him) gets some positive buzz, it could lead to a Heroes for Hire film or TV show.
