there is a video of the Blue police car figure in post #2 by Pascal, Post #1 is just the yellow jet and red Firetruck and the combined mode with the police car being the head. As of now I have very little interest in this set...I have to see the other 2 gestalt modes to make a definite decision. So far I don't think I'm jumping on it at $140 + (BBTS, TFsource prices) and shipping. Hope to see the remaining vids pop up sometime.
I don't know about you but I get a serious Superhuman Samurai Cyber Squad vibe from these combiners...nothing makes me feel like these are Transformers at all.
