This wasn't "Pixar" though. It was just Disney Animations Studios. Pixar's next movie is something called Inside Out. Wiki has this as a description:
"Riley is uprooted from her Midwest life when her father starts a new job in San Francisco. Riley (Kaitlyn Dias) is guided by her emotions - Joy (Amy Poehler), Fear (Bill Hader), Anger (Lewis Black), Disgust (Mindy Kaling) and Sadness (Phyllis Smith). The emotions live in Headquarters, the control center inside Riley's mind, where they help advise her through everyday life. As Riley and her emotions struggle to adjust to a new life in San Francisco, turmoil ensues in Headquarters. Although Joy, Riley's main and most important emotion, tries to keep things positive, the emotions conflict on how best to navigate a new city, house and school. But when Joy and Sadness get lost, meaning Fear, Disgust and Anger are at the helm, the two have to make it back to headquarters before Riley becomes emotionally unbalanced, while at the same time, the two opposite emotions learn how to coexist and balance themselves in Riley's life."
Aside from that, PIXAR is also working on "The Good Dinosaur", "Finding Dory" (Nemo sequel), "Toy Story 4", "The Incredibles 2" and finally "Cars 3".
