Just so everyone knows my stance, and why I keep turning down some ideas, like the firetruck or tow-truck is because just as this movie is adding new robots, it is very possible that the next movie will also add new robots. I don't want to limit possibilities of seeing old favorites because their vehicle mode has been taken. Some, like the sports cars and vans, etc., can easily be changed, but things like a firetruck or a tow truck, etc. are kind of who the charachter is. A lot of the Decepticons are forced to take on new modes either due to their outdated status (a microcasette recorder) or that the writers do not want to get into too much mass shifting (a microcassette recorder or a handgun)(although, wasn't there a little bit of mass shifting with the Allspark there at the end?) so they are forced to change. I think for the most part, they have kept pretty faithful to the charachters, so if the option is there for them to take on their old self, close to their old self, or not step on the form of another autobot that could potentially be in a sequal, they should respect those posibilities. Many times on the cartoon, their alternate form was based on their personality:
From Wikipedia:
"In the original
Transformers toy line,
Hoist is an
Autobotwho functions as a repairman for the team, keeping them to a tight maintenance schedule. Hoist is confident and sometimes rash, brave, tough and loyal. He transforms into a green tow truck."
"
Inferno is a fearless Autobot who has a firetruck as his vehicle form. He relishes the attention he gets for saving lives and extinguishing fires any chance he gets, but Inferno's intentions are always noble, though he rarely gets involved in the battles."
"A commander could want no finer a soldier than
Ultra Magnus. Despite his incredible fighting skills, courage and unmatched talent for improvisation on the battlefield, Ultra Magnus is most comfortable when carrying out orders, and is naturally uncomfortable if the mantle of leadership should ever find itself placed upon him. Ultra Magnus is armed with missile launchers capable of hitting a target 30 miles away, and transforms into a car carrier able to transport his fellow Autobot troops."
