OK, so maybe it is still over two years away, but FOX has put Alvin and the Chipmunks 4 on the calendar for holiday 2015. So you can start planning your Chipmunk parties now. Or don’t. That’s actually kinda creepy, so please don’t plan chipmunk parties. No casting has been announced, but I would expect to see Jason Lee and David Cross back. It’s not like they are suuuuuper busy.
