One is of the previously reported new deluxe Bumblebee figure, and the other is a remold of the deluxe Barricade figure from the first Transformers movie.
Please note that this should not be taken as evidence that Barricade appears in the sequel.
The extendable claw gimmick seen on the toy is likely a nod to his appearance in the first film, and there is nothing else to suggest that Barricade will appear in Revenge of the Fallen.
