If, in fact, this is a legit posting of these scan codes then I would have to say that Warpath will not be a repaint of the Darkmount/Skullgrin mold. Hasbro doesn't usually move that fast on putting out a 3rd use of a mold in such a short period of time and wouldn't be so dense as to attempt it with such a big name character. That Warpath has already been given the mini-bot treatment recently certainly won't hinder his getting a size upgrade and I'm inclined to think that they would at least try to stay close to his Legends class design for this new version.
As for Arcee, she may wind up being a re-mold but I'm betting that it will be one of the previously used cars and not the Wreck-gar mold. No matter what, Hasbro has always made sure that she has curves in her previous incarnations and Wreck-gars mold totally does not fall in that category.
It also would not surprise me if both of these were actually done for WFC. They know that the fans are screaming for more WFC figures, especially Starscream, and since they released Cliff before 2011 it wouldn't surprise me to see at least 3 more figures come out to supplement the Cliffjumper addition to the line. Why end a good product line with a re-mold when you can end it on a "fanboy" high note and lots more cash?
