I believe so, since it with the smaller ones, and the Brachiosaurus was supposed to be the next one released in the PVC line. It looks pretty good for a PVC.
Does anybody know if or when they will release the 1/15 scale Prime 1 version? There is a short window on getting the Iron Studios 1/20 scale version. I have to have a brachiosaur and don't want to hold out just to find that Prime 1 is not making theirs. Thanks.
No. They have only shown a picture of a prototype though, so it will probably be a while. It might go up for preorder after the summer Wonder Festival in Japan if it revealed, but it would not surprise me if it is not there.
