Unicron.com has posted a one-on-one demonstration of Siege Titan Class Omega Supreme and Commander Class Jetfire conducted by none other than John Warden! Warden shows off many of the features of the figures, including Omega's very impressive light-piping, and details a lot of the ideas behind his creation.
Omega is intentionally scaled to Combiner Wars Titan Class Devastator. His tracks are designed to be two Micromasters wide, and those who buy multiple Omegas can create a Guardian Superhighway for your Micromasters to traverse. The tank's Micromaster compartment is likened to the Thunderbirds TV series. He has rocker ankles, as is standard for Siege, and is described as Religiously Parts-forming, and thus in the spirit of the original toy. Omega's tracks use the same connectors as the Titans Return bases for maximum interconnectivity!
Jetfire is a new class, Commander class, to keep the character in scale with the rest of the cast. He's very heavy! Springloaded doors hide the robot head when converting the figure. His 5mm hand ports are hidden when his hands are open, which is a great feature. His faction sigil flips around so he can be an Autobot or Decepticon. His armor connects to the jet mode as a drone. He has a working landing gear, and the cockpit opens and features a removable "Computer Brain to seat Titan or Prime Masters. He also has handholds on his undercarriage to function as a dropship!
