Don't know if this is meant to be sarcastic, but if true, we are heading for even more Pixar sequels. What has happened to them? Why so many sequels suddenly? Is this now finally Pixar being "Disney-fied"?

Pixar’s upcoming direction is moving away from [its] winning formula [of original movies]. Including “Monsters Inc. 2,” three of the next four scheduled Pixar features are sequels to past films — the other two being “Toy Story 3” which comes out this June, and a “Cars” sequel scheduled for June 2011. Additionally, “A Bug’s Life” sequel is slated for release in winter 2013. To put this in perspective, it’s been more than ten years since Pixar released its one and only sequel, yet the studio plans on releasing four within the next three years. If you ask me, Pixar is only setting itself up for failure.
