Sigh: Optimus Prime, eh?
I don't want to sound like an obnoxious fanboy, but if this is true, it's just all wrong. This'll make no sense I guess, but there was just something majestic about Prime in his classic form. Changing his shape, colour, and adding flames to him just reduces him to... to exactly what I disliked about Hot Rod in the movie. There are certain types of characters that you can care for without relating to at all. Some people are just too authoritative, too closed off, too much of a fortress... and that's exactly what prime was. He wasn't cool because of how he looked or his weapons or the lines he delivered... he was cool because he was simply a force to be reckoned with.
And now I've gone and wasted a whole post on possibly-fake leaked photos from a movie that doesn't come out till next year. Sigh again.
