Someone has obtained the Platinum Edition Dinobot 5-pack, and shared photos of the toys in both modes.

Looks like they are a smoky translucent plastic with chrome coated parts, to give them a ghostly look.

Apparently the Optimus toy in the Leader 2-pack is also of translucent coloured plastic, so these will match the look of that one a bit.

The five Dinobots are Voyager Grimlock, Voyager Slog (Sludge), Deluxe Strafe, Deluxe Slug, Deluxe Scorn... which is the four Movie Dinobots plus Slog for some reason.
