Looking at those in-hand pictures, I suspect the reason they haven't gone with the pinstriped flame outlines is that putting them on would mainly be for the sake of the vehicle mode. Given the lengths to which they've gone in lavishing this bot mode with all those painted details and accessories, they're probably not expecting too many people to be displaying this in truck mode.

It's still a lovely truck, but the bot mode is really where the action is for this one. Especially nice if you do have a chromed-up buster to have nearby in truck mode.
