Inevitably, given the movie and Classics like, we're going to get an Alt-Bumblebee. Maybe not as a VW Bug, but still. Anyway, you know that one old Dreamwave G1 v.3 cover, where it's Bumblebee with a gun as big as he is? What if they designed an Alt-Bumblebee (using whichever befitting car), but only used 2/3s of the car for Bumblebee, whereas that last third would be used to make him a BFG? Ie, the entire area under the hood, instead of hiding arms, legs, etc, would hide a massive cannon, and the area consisting of the driver's cabin to the trunk would transform into the robot itself? This would allow the designers to keep Bumblebee a smaller robot while also providing him with a very cool and unique feature that sets him apart from the other Bots/Cons. Personally, I think this would be the best route to go with 'Bee; I mean, the alternative is to give him a robot mode in scale with his brethren, and to me, that doesn't seem in keeping with his history and character (hence why the Classics one is short, too).
