With the aim of Studio Series being screen accuracy, they are basically working on a scene that was made last minute, with CGI models that have no alt-mode + are technically reshells of the main character models, so if they all have the same weapon because they couldn't do more models then so be it, the toys would also reflect that.

The gun Elita-1 uses to fire on Megatron is the "RT-5 Anti-thermo Blaster" with the "SR Hushfuze" barrel attachment which is included with both releases of the Siege Chromia mold.

Transformers (sculptures), 10-foot (3 m) tall sculptures of Bumblebee and Optimus Prime in Washington, D.C.Since his conversion from 1977 Camaro to 2006 Camaro Concept, Bumblebee's alternate mode continues to evolve throughout the film series. Bumblebee is one of the smallest and physically weakest Autobots. While his stature allows him to do his job better than most Autobots could manage, he is self-conscious about his size. Maybe this is why he makes fast friends among the humans. He looks up (so to speak) to the other Autobots, especially Optimus Prime, but what he doesn't realize is that they look up to him. He may be small, but he's brave, and he's one of the most well-liked Autobots around. Bumblebee already has the respect he craves. If Bumblebee decided that the Decepticons destroying farmland was a more important matter to attend to, they are ambushed by the Decepticons almost immediately, and are subsequently destroyed.
