I am not really that surprised over this comming out sooner (I would have been surprised if this was a year ago). I read that the first set was in the top ten its first week, so I figured this set would be released this year. It's amazing that the first set sold well enough, as I don't think Dinosaurs reruns are currently on TV, and I don't think this show is as popular as The Simpsons, Star Trek, Friends, Cheers, or even The Muppet Show or Sesame Street. The people who provided the DVD commentary for The Simpsons episode Black Widower must have been wrong when they said that "nobody remembers Dinosaurs anymore".
