Concept art for Transformers has recently hit the web from Transformers video game concept artist Frankell Baramdyka. The images seems to show of various new Cybertron locations and new characters that seems based on the movie art style but could also fit what we have seen so far for Transformers: War for Cybertron video game.
The images initially showed up on Baramdyka's blog (now removed), and spread to various sites including TFW2005 (for images on this post), io9.com and Shogun Gamer.
Another theory, advocated by io9, is that the artist was hired to begin work on the video game version of Transformers 3. That would suggest scenes from Cybertron, not out of the question considering the recent comment from Hasbro CEO Brian Goldner saying the movie would return to "core mythology". Thanks to Avatar, visiting strange new worlds is no longer a bad thing to studios. Still expensive though.
I am leaning to thinking this was War For Cybertron art and not for the movie but its going to be a while before we know for sure. Thanks to Gregory for the link and images. Also to Katie for her link.
Update: Had to remove images per DCMA request from somebody, I assume Paramount or Activision. Can't say who exactly because notified via google. Anyway, if had doubts about the legitimacy of the images, there are none now.
