Hey, ckecking back the video, a stand says "Animated film and merchandise coming in 2014!". Does that mean that they'll bring out collectible figures or something? Cool!
unfortunately I think Action Figures would be out of the question due to the licensing rights for toys are at different companies. WWE toys are licensed to Mattel and Scooby is licensed in the US to Character (he REALLY needs to goto a bigger company like Hasbro or Mattel IMO). It's possible that one could sub-license out, but I don't think it would be likely.
According to Blu-Ray.com, special features include "Behind the Scenes with Scooby-Doo! and the WWE Gang". It was about time they put a behind-the-scenes special in a movie! We have not seen one since Lake Monster.
