I agree with Dirge - there's no way that is going to be retooled into anything decently-resembling Sunstreaker in robot mode, although they might stick a supercharger engine and a new head on it, recolour it yellow and call it Sunstreaker anyway. Although I'd prefer it if they just did a straight yellow recolour and call it Tigertrack or Spin-Out. They generally recolour Masterpieces into the ground, so G2 Sideswipe (fingers crossed for a bandolier accessory) would be awesome. Red Alert is inevitable. Deep Cover and Clampdown would be sound choices. Breakdown is likely. Laster and Deadwheeler would be scraping the bottom of the barrel.
