Pixar's "top secret project"

I was recently reading Pixar Wiki, when this came across.
“The company’s fifth film was tentatively slated for release in 2002, was a top-secret project to be directed by Andrew Stanton, who had worked on both Toy Story and A Bug’s Life.”

What was this film?. Google search results only comes across this.

How peculiar. I would assume it was Finding Nemo, if you take into account the film was delayed one year.

It seems like the only logical conclusion for it.

Possibly, but nowhere mentions about Finding Nemo being delayed. :blush:
