User blog comment:Wonderkidrobin/Press Release for Young Justice Invasion: Part One- Includes Season 3 pick up??/@comment-5616790-20121013203059

No announcements have been made from cartoonnetwork or DC.

But the voice actor of impulse said production is done or soon to be. http://www.theouthousers.com/index.php/news/118503-no-more-young-justice.html

But i would wait till we get an announcement from Cartoonnetwork or DC because, his statement sounds inaccurate.
