TFormers has recently put up an article featuring images of some very G1-inspired, but distinctly movie-esque renditions of Soundwave and Shockwave, which very well may be early concepts for Transformers: Revenge of the Fallen 2 (or not: read below).  Or they may very well be impressive pieces of fanart.  Either way, they're worth checking out.  Be sure to discuss your crackpot theories, educated guesses, and wild-eyed speculations, in Toymaker's thread on our forums.

 UPDATE: Master Fwiffo informs us that these are pieces of fanart by Transformers Movie message board user "Mit."  Consider this rumor debunked.
