Titans

We’ve known since 2014 that a Teen Titans TV series was on its way. At that time, it was announced that TNT ordered the show and Akiva Goldsman was set to write the script. The show was expected to begin with Robin emerging from his mentor’s shadow to establish his own team as Nightwing.
However, by 2016, the project was scrapped.
The new series, with Goldsman again writing the script and Geoff Johns and Greg Berlanti producing, was announced this year. According to that announcement, the series is set to debut on DC’s new direct-to-consumer digital service in 2018.
So far, Teen Titans Dick Grayson, Starfire, and Raven are the only confirmed characters.
Runaways

Before The Avengers, The Runaways was expected to be Marvel’s first ensemble movie. The script, written by Drew Pearce, was apparently very good, as Pearce was asked to write for Iron Man 3.
Rumor has it that while it was never used, Hulu’s new Runaways series is based on Pearce’s script.
In Marvel’s Runaways, a group of teenagers with superpowers discover that their parents are a group of supervillains known as the Pride. In order to atone for their parents’ deeds, they unite to form the Runaways.
Scheduled for a 2018 release, the new show hasn’t put out a trailer, although there’s been a leaked first look. But there’s still plenty of time for a trailer to pop up.
