Concept arts are sometimes great, there will always be reasons for the final product being what it is but most of the ideas thrown out in the concept phase usually has a lot of interest. I still remember the concept art for how Mechtech weapons was going to pan out. Funnily enough pic related made it into the DOTM game and it was pretty cool there though sadly it was a boss fight with Optimus as the boss himself.
