gold version of roidmude? now Bandai have a tamashii premium recolour version for Brain and Freeze

Super Deadheat looks like it can be a fusion of Drive, Mach, and Chaser because of the Mashin Chaser-like body. Also, I found this picture that gives us an idea of Super Deadheat based on the silhouette:

Yeah that's a widely known photoshop. It's a stock image of Mashin Chaser that's been color shifted and had Drive's head and Mach's Drive shopped onto it. It does give us a decent idea of the direction they're going in but until we see the real deal we won't know for sure.
