It better be. I also want to know if Fred designed the new utah? It looks like something of his. I have similar feelings about the dilo but I assume if he did the utah he did the dilo too.
I'm really not sure. I don't know if they always have a concept before Jake models them or not. It's probably a fairly safe assumption that Fred might have, if there was indeed a concept.
I think so. The way I notice is the fore-claws. They look extremely similar to his hand designs.
