Flickr [via /Film] got a load of concept art for "Transformers: Revenge of the Fallen".  At this point, you have to wonder why they're holding back on a trailer since they can no longer obscure these Autobots and Decepticons and force us to go frame-by-frame in order to identify them.  We also have definitive proof that Megatron will return (why bother lying about that in the first place?) and I have to say that The Fallen's action figure does not do him justice.

Check out the concept art below and click here to see the full gallery.  "Transformers: Revenge of the Fallen" hits theatres on June 26th.
