I'd rather wait for a Dinobots only game. We all know how big Sludge would actually be. I think cramming him into FOC would only be an injustice and a half assed attempt at best. Heck, I'd be happy with a DL add-on for FOC that concentrates solely on the Dinobots to extend the life of FOC. Then they can bring out Sludge proper;y instead of shoehorning him into the titan category, when he would be MUCH larger than a Titan.
