In a L.A. Times interview, Stanton explains directing ‘John Carter’. About three-fourths through the interview, he mentions he’s directing the ‘Finding Nemo Sequel’:
After “The Abyss,” Cameron returned to the film that had launched him, ”The Terminator,” and made “Terminator 2: Judgment Day.” Similarly, Stanton’s next directing project will be a sequel to “Finding Nemo.”
“What was immediately on the list was writing a second ‘Carter’ movie,” he said. When that went away, everything slid up. I know I’ll be accused by more sarcastic people that it’s a reaction to ‘Carter’ not doing well, but only in its timing, but not in its conceit.”

Late Thursday evening, Lee Unkrich shared the following on his twitter:
Tomorrow is a big day that may determine the next four years of my life. Wish me luck.
The next day, he was likely pitching an idea or awaiting a decision on whether or not his next project would receive the greenlight. Well, it looks like things went fairly well, as on Friday he shared a tweet (that has since been taken down) that read, “Weekend: Relax. Monday: Get started on a new movie.”
As to what the film will be about and whether it will be an original film or a sequel, we haven’t got a clue.
The unannounced film will likely be in production for about four years, giving it a release date of sometime around 2015 or 2016.
