If you are in the United States, you may not be able to get it for another couple of weeks. (Issue 133) 3D World mailed me mine since I was a contributor so I've received it ahead of the stores. 

3D Artist (3Dartistonline.com) also had  C7 in their last issue (had a tutorial in that too!) so if you can track that down, you'll find it there too.
