During all the festivities of CinemaCon in Las Vegas this week, the folks at Pixar announced several things. One being that their latest film Brave would help test Dolby’s Atmos format, a revolutionary new sound system that we reported on yesterday. The other — perhaps bigger — announcement is that they gave updates on three upcoming projects, all from original stories and all featuring Pixar veteran directors. Can’t wait to hear about Up co-director Bob Peterson’s dinosaur movie? How about Pete Docter’s trip inside the human mind? Or maybe you’re interested in Toy Story 3 director Lee Unkrich’s film about Dia De Los Muertos. It’s an interesting slate, about which we’ve compiled all the available details just after the jump.
