the preview bumble IS the rotf bumblebee (along with cannon bumblebee).....those are both the same....
Both those pictures are of the Preview Bumblebee. The other Deluxe, Cannon Bumblebee, has flip out shoulder cannons, and a new torso and arms sculpt.
It's much more than that - for a start, both those pics are of Preview BB. For Cannon BB, the torso & arms were remoulded from scratch, to make the arms more accurate and to allow the new cannons to work in both modes. However, the chest area was seen by many as a step backwards in terms of complexity and accuracy.
OK, I got it now. I was calling Preview BB, Deluxe BB, and calling the other one Cannon BB, since that's what's on his package. Close thread now, please. Thanks, guys.
