Geoff Johns greeted 2017 with a list of the top five DC events he's looking forward to in the new year -- including a new television series that he promises "will be announced soon."

The tease from DC Entertainment's president and chief creative officer arrived Saturday night on Twitter, at the end of a rundown of several of the current TV shows based on DC Comics properties: The CW's "The Flash," "Arrow," "Supergirl" and "DC's Legends of Tomorrow," and Fox's "Gotham" and "Lucifer."

The new year also sees the premiere of the NBC comedy "Powerless," and new seasons of "iZombie" and "Preacher." In addition, WGN America and Syfy have ordered pilots for "Scalped" and "Krypton," respectively, and Fox has made a production commitment for a "Black Lightning" pilot. However, it's unclear from his Tweet whether Johns might have been referring to an announcement of a series order, or a completely new project.

Beyond animated series like "Young Justice" and "Freedom Fighters: The Ray," projects known to be in development include "DMZ," "Ronin," "Y: The Last Man" and "Unfollow." But we shouldn't forget "Teen Titans," which stalled at TNT, and the long-discussed adaptation of "The Sandman," which has bounced between television and film for years (it's still in development for the big screen, but its most recent screenwriter bailed out, saying the comic should be adapted for television).
