It looks like way of the Playmates Toys website, they have confirmed Bebop and Rocksteady for the Teenage Mutant Ninja Turtles Classics Series 2. And according to ToyNewsi whom reached out to Playmates for confirmation, these will be the only two figures in Series 2. So it looks like fans will have to wait a bit longer for Classic Shredder, Splinter, Krang or Foot Soldier. There are no images at the moment, but Playmates Toys will be showing both figures off at Toy Fair next month in New York.
Update: Playmates has confirmed for us that wave 2 will only include the two figures of Rocksteady and Bebop, so I guess we will have to wait a little longer for Shredder and any others. Playmates also confirmed for us that we will get a look at both Rocksteady and Bebop at Toy Fair next month, so stay tuned.
