Haven't seen these before: IG-TF004A - Masterpiece Big Trailer - Original Colors IG-TF004B - Masterpiece Big Trailer - Black Version And the rodimus box is being sold seperatley: MP-09 - Masterpiece Rodimus Prime - Showcase
Those trailers have been on pre-order since late 2009, IIRC. I don't think we'll ever get them. That MP Roddy showcase box thing is neat, but not $19.95 + Shipping neat, IMO.
