The next batch of toys to be called "Authentics" are not part of the existing sizes, but since they are on the cheaper side, I think we could see them here at grocery stores here.
There are three types revealed - non-converting Cyber Battlers figures (just three characters - Optimus, Bumblebee, Megatron) for us$5 each, plastic face masks (Optimus and Bumblebee - done before) for us$5, and Mini-Racers (using 5 of the 6 Rescue Bots Mini-Racers moulds) for us$4.
Three of the Mini-Racers are identical to the Rescue Bots versions (Optimus, Hoist, Bumblebee), while two are completely redecoed as different characters (Whirl is a dark pink to be Arcee, while Hotshot is black which could be Trailbreaker). That left Heatwave Mini-Racer unused, and in the master carton of 6 they have two Bumblebee toys.
