More car companies?

[FourHorsemen]

Now that the movie is released, I wonder if other car companies feel horrible about not getting on board with the film.

and would this open up more possibilities with the future autobots/decepticons in a sequel?t:

Car companies don't have to get on board for a film to use their vehicles. Licensing for toys is a different thing.

I wonder if they will make Alternator versions of the movie models? The current toys are too small.
