I think whatever fits in Whirl's cockpit can fit into Jetfire's. Be cool if Hasbro uses Roadbuster, Jetfire and whirl as Transformers VS GI Joe exclusives with mini-driver figures of Ace, Wild Bill and Double Clutch. Jetfire in Skystriker colors, Roadbuster painted like Hound(to look like the VAMP) and Whirl in green as the Dragonfly. Interestingly enough, G1 versions or all 3 used Takatoku 1/55 molds from Macross and Dorvack. If Roadbuster is an all new mold than things will have come full circle for those 3 with new versions/molds of each in the Generations line.
