Some new product images have been found for upcoming Battlepacks and the first Minicon 4-pack.

The Minicon 4-pack are just redecos (the two cyclone/cannonball Minicons should be out before this 4-pack is released)... of Backtrack, Swelter, Beastbox, and Undertone.

While the Battlepacks are in two waves of two, with a new mould robot that is smaller than a Warrior class toy, packed with armour parts and a Minicon... which should end up being the same price as a Warrior class toy.
Wave 1 - Optimus & Bludgeon, Sideswipe & Anvil.
Wave 2 - Bumbleebee & Major Mayhem, Grimlock & Back.
