Alvin and the Chipmunks 3 coming December 2011!?!?

Seeing as how the first two generated a worldwide box office of 790 million plus this no big shock. The question is what can they possibly do for a third go around? I think they kinda milked the concept for all it's worth in the first two flicks, dont you? Another head scratcher sequel coming our way happens to be Pixars Cars 2. I wasn't exactly wild about the first cars movie. Why don't they get there heads screwed on straight and give us Incredibles 2 all fragging ready? Now thats a concept that has plenty of life in it for a true animated franchise!
