Now, correct me if I'm wrong... but I read a while ago that this very argument is one of the reasons why GM seems to be the SOLE company providing vehicles to the movie universe, not just the fact that there's an exclusive deal. In my opinion, car companies need to get off their high horse. What happened to the old saying: Any news is good news, even if it is negative? If your car is cool, no matter what faction it is associated with (and this applies to more franchises than JUST Transformers.), it will enhance the overall appeal of the media in question! It gets your brand out there, and could possibly translate into big sales! But then again, there ARE 2 sides to the coin. The movieverse Decepticons, even though the hardcore transformers fans know what their faction is fighting for, it's very obscure to the main audience, and that maybe why car companies are reluctant to hop on board: they don't want their cars to be portrayed as mindless killing machines (what they could think the decepticons are). I say that there needs to be a change, a change in the reason of why the Decepticons are fighting, and to REALLY sell that point. To make it well known that they are fighting for the survival of their species (despite the ulterior motive of taking over the universe). Maybe if the opposing faction had a more sympathetic reason of waging war, it would open doors to having more of the alt modes that we want on specific characters. Anyways, that's my little rant. It's messy, I know... but please comment and discuss.
