First, I'm sorry if this has been mentioned before. I was looking at the trailer for ROTF the first time in glorious 720p on the laptop tonight and I noticed something in the scene where Sam is being pinned down. I took a screen cap and attached it below, what do you guys think? I think it closely resembles the leg as seen in the review of FAB ROTF Megatron done by GenZhao. It kinda looks like tank treads. on the back of his leg.
