The news finally broke regarding future volumes of the new TMNT Animated Series. Looks like we're going to start getting closer releases again as well, or at least I hope so. Volume 15: Ways of the Warrior - Alien Invasion and Volume 16: Ways of the Warrior - When Worlds Collide have been given release dates according to DVD Empire. No confirmations what episodes will be included on these volumes, but Vol 15 will likely include Episodes #54, #55, and #56. And Vol. 16 will likely include Episodes #57, #58, and #59. You can preorder both of them right now from DVD Empire at the following links. No artwork available for the DVD's as of yet, but probably in the next couple of weeks some will turn up.
