These were found by Hurrijak at The Technodrome. In the past, he/she's found what ended up being the entire 2013 line-up on his work computer, so I have no reason to doubt that all of this is legit:

The Technodrome Forums - View Single Post - 2013 TMNT Figures

Vehicles: Shell Flyer, Grass Kicker
Role Play Item: Deluxe Mask - Casey Jones

Figures: Mutagen Raph/Don/Mike/Leo with Ooze, Raph Barbarian (likely from the "Larp" series), Deep Cover Raph/Don/Mike/Leo, Squirrelanoid, Robotic Foot Soldier, Battle Shell Raph/Don/Mike/Leo (already confirmed), Leo Knight Larp, Don Wizard Larp, Mike Elf Larp, Rocksteady, Bebop, Tiger Claw, Slash, Mutagen Man, Rahzar, Kirby Bat, Casey Jones.

Interestingly, they're all at basic figure price, so I have no reason to believe that Robotic Foot Soldier, Rocksteady, Bebop, and Rahzar (all previous figures that have not been confirmed for the new show yet) are from the Classics line or the re-releases. Also... Kirby Bat? Does April's dad mutate?! Bizarre.

Squirrelanoid, Tiger Claw, Slash, Mutagen Man, and Casey are characters already confirmed for next season.
