Things were busy at Disney’s D23 Expo this past weekend, where several tasty nuggets of information concerning upcoming Pixar titles were dropped.

We now have additional details about Pixar’s upcoming fantasy/adventure Brave, as well as the next Pixar flicks that’ll be directed by Peter Doctor and his Up co-collaborator (and Finding Nemo co-writer) Bob Peterson, respectively.

Anticipation for Pixar’s next release, Brave, remains quite high, despite the so-so reception for the studio’s most recent release, Cars 2. This is a film company renowned for its originality and creativity – and based on the Brave teaser trailer, Pixar’s first venture in the fairy tale princess genre should boast its traditional mix of beautiful computer-generated animation and solid storytelling. At least there won’t be any Larry the Cable Guy in this one, right?

On that note – check out the new official synopsis for Brave:

Since ancient times, stories of epic battles and mystical legends have been passed through the generations across the rugged and mysterious Highlands of Scotland. In “Brave,” a new tale joins the lore when the courageous Merida (voice of Kelly Macdonald) confronts tradition, destiny and the fiercest of beasts.

Merida is a skilled archer and impetuous daughter of King Fergus (voice of Billy Connolly) and Queen Elinor (voice of Emma Thompson). Determined to carve her own path in life, Merida defies an age-old custom sacred to the uproarious lords of the land: massive Lord MacGuffin (voice of Kevin McKidd), surly Lord Macintosh (voice of Craig Ferguson) and cantankerous Lord Dingwall (voice of Robbie Coltrane). Merida’s actions inadvertently unleash chaos and fury in the kingdom, and when she turns to an eccentric old Witch (voice of Julie Walters) for help, she is granted an ill-fated wish. The ensuing peril forces Merida to discover the meaning of true bravery in order to undo a beastly curse before it’s too late.

Untitled Dinosaur/Human Mind Projects

Monsters University will hit theaters in Summer 2013; Pixar’s original offering of that year will follow in the fall, with Bob Peterson making his solo directorial debut. It has been revealed that the latter project takes place in an alternate reality where humans now co-inhabit the modern world with dinosaurs.

Here is the official logline for Peterson’s “hilarious, heartfelt, and original” movie:

What if the cataclysmic asteroid that forever changed life on Earth actually missed the planet completely and giant dinosaurs never became extinct?

That logline recalls less-than-stellar titles like Super Mario Bros. and We’re Back! A Dinosaur’s Story, but in Peterson’s hands, the premise should turn out much better. It’ll at least be fun to see how Pixar animators bring the ancient creatures to life – whether in a more cartoonish or realistic style, a la Jurassic Park. So long as this doesn’t play out too much like a contemporary riff on The Flintstones, it’s all good.

Check out the preliminary logo for the project (via Collider) below:

Peter Doctor’s next project, by comparison, sounds like one of the most ambitious impending Pixar flicks on the horizon. Just check out the logline below and see what we mean:

Pixar takes audiences on incredible journeys into extraordinary worlds: from the darkest depths of the ocean to the top of the tepui mountains in South America; from the fictional metropolis of Monstropolis to a futuristic fantasy of outer space. From director Pete Docter (“Up,” “Monsters, Inc.”) and producer Jonas Rivera (“Up”), the inventive new film will take you to a place that everyone knows, but no one has ever seen: the world inside the human mind.

The Playlist is reporting that Oscar-winner Michael Arndt (Toy Story 3) is working on the script for this film, which reportedly examines the process by which ideas are formed. Doctor could approach that premise from an angle similar to that in Monsters Inc. – by exploring the mechanics of an (pun not intended) imagined world where our thoughts and ideas are literally designed.

Did anyone else think “Pixar does Inception” after reading that description – and get really excited by the prospect?

Brave will arrive in U.S. theaters on June 22nd, 2012.

Monsters University is scheduled for theatrical release on June 21st, 2013.

Peterson’s dinosaur movie will hit theaters on November 27th, 2013.

Doctor’s “mindtrip” project will be released in theaters on May 20th, 2014.
