Unreleased and miscellaneous

• Hot Rodimus was later re-released as a Toys'R'Us exclusive with purchases of THS-02 Convoy.
• Trade show images originally suggested a third wave of Smallest Transforming Transformers, which would have added the then-unreleased Hot Rodimus, as well as still-unreleased versions of Skids, Tracks, and Megatron's stock and silencer accessories. Skids and Tracks were reportedly unproduced for cost reasons.
