Hello! Since I knew of Josh Nizzi doing the covers for the ROTF prequel, I stumbled across his official page. Three days ago, he updated it, and well, there's every cover from Alliance/Defiance #1 to Revenge of the Fallen #4. You may have already seen the latter, but not the finalized one, with the Fallen behind Optimus. Here I leave all the links to all the covers, enjoy them: Alliance #1 Alliance #2 Alliance #3 Alliance #4 Defiance #1 Defiance #2 Defiance #3 Defiance #4 Revenge of the Fallen #1 (Optimus and Bumblebee) Revenge of the Fallen #2 (Devastator sucking Prime, Sideswipe and Bumblebee) Revenge of the Fallen #3 (Upgraded Optimus standing against fallen Starscream) Revenge of the Fallen #4 (Megatron vs. Optimus, Fallen in the background) Also, in the website, it looks like there's going to be a Revenge of the Fallen feature soon.
Hey, the cover for ROTF Adaptation 4 is actually a reworked version of the rejected cover for Defiance issue 4. The stock low-res publicity render of The Fallen is photoshopped into the background. Original Defiance issue 4 cover It was assume Paramount or Bay or whatever had IDW reject it because it showed Megatron's ROTF body, back when Bay was swearing up and down Megatron wasn't coming back. This nonsense also affected Nizzi's cover of Defiance issue 3 , which showed ROTF Megatron, but it was changed to 2007 movie Megatron a few months later. Wreckage (Movie) - Transformers Wiki
