At 36:14, it's said that Welcome to the Wayne has been renewed for a 20 episode second season.
EDIT: They took down the video (I'm guessing it was because it was uploaded a day early), but when they reuploaded it, they removed mention of it being renewed. I guess they couldn't reveal that info yet.
Henry Danger will be filming 2 more episodes in season 4. Considered it's been highest Nick's live action, it's unknown whether season 5 will be renewed or not. Jace confirmed he has not yet filmed the official closure for the season yet.
I guess I should've also mentioned that when ABC is currently at season 5, it renewed for season 6. N@N is currently airing first four seasons. The ratings for N@N are averaging 0.4-0.6 total viewers.. I'm not sure what ratings N@N is expecting..
