The Incredibles trailer

If you trailer it, the web will link to it. The Incredibles looks very funny. I suspect it will be the most challenging of their movies yet from a humor perspective because the characters are human rather than creatures or toys. Pixar has gotten a ton of mileage out of anthropomorphic jokes, and they won't be able to go to that well this time.
To some degree. The characters are still superheroes, or not normal humans, so they'll be able to capitalize on the "superheroes have mundane human problems" jokes also, e.g. the laundry joke in the trailer. A more solid formula for consistent quality than the usual sequel-itis Hollywood finds so reassuring.
