Deluxe Bumblebee is only new from the waist up, almost. He'd definitely be classed as a remold.

Edit: There are actually two Deluxe BBs: Preview is the one mentioned above, but also there is Cannon Bumblebee which sports flip-out shoulder cannons but sacrifices a screen accurate chest/torso in the process. As far as I'm aware this one from the waist down is the same as all other BB molds too.
