Buzz Lightyear’s ready to fly for a fourth time, but Pixar isn’t totally committed to doing another Toy Story movie just yet.

Tim Allen has agreed to reprise his role in another sequel, but the story’s neatly wrapped up thus far. Toy Story 3 director Lee Unkrich said he tried to “end of the story of Andy and his toys and bring that story to a close in a really nice way.”

But that doesn’t mean the door is completely closed - he also said “we know that people love the characters…and would hate to say good-bye to them completely.”

We do know this: the entire gang of toys will be appearing in a short film, which will air before the opening of Cars 2 (which opens in June 2011).
