I would like DC to make a revamped version of the Justice League, but this time as a prequel to Young Justice using the adult justice league characters. (Batman, superman, wonder woman etc).
Marvel wise, an animated young avengers show with Spiderman and some others would be cool.
Anew season of the boondocks. While I know that both John Witherspoon and Charlie Murphy have sadly passed away. With the current state of the country we definitely need new episodes.
