But various geek sights are hosting the concept art for the pitch, though...like Topless Robot...so you can imagine it.
Looks like there would have been a transforming Batmobile for Bruce Wayne and an invisible jet for Wonder Woman. Optimus appears to be sorting a Green Lantern ring, while the Flash takes on Insecticons and Aquaman tackles the Seacons.
So howabout? Who would be your favorite Transformers / DC Hero team up or versus match?
(I don't see how they could have avoided a Blue Beetle / Bumblebee pair...see...because they are both beetles...and often comic relief...)
