Euoplocephalus egg won't be a bad idea, but I don't hope Sideshow spend too much time repainting the PAST (just let it go), I hope they can put more effort on new dinosaurs.
Well, I think Dinosauria line never ever be popular, and it doesn't have to, I don't care 'popular', it's always a small group. I think SS has their schedule, we can't do anything. Lets just wait, I think we always wait longer than other line in the past 5 years. Like Dyscrasia said it's all about business stand point. So don't be too disappointed. I think it will release before early October.
It seems that Ceratosaurus will be the only one dino that we can receive in 2016. Maybe they decide to make 1~2 dinos per year.
The following is the rough history list of past dinosaurs with their corresponding 'ship year', the year that they shipped, the year that we got. So average only 1~2 NEW dinosaur we can unbox each year since 2011
:
2009: T-Rex-VS-Triceratops→Carnotaurus→Tyrannosaurus-Rex→Styracosaurus, and Brachiosaurus Hatchling
2010: Deinosuchus-VS-Parasaurolophus→Allosaurus VS Camarasaurus→Protoceratops-VS-Velociraptor→Spinosaurus
2011: Tupuxuara-Pterodactyl→Apatosaurus
2012: Stegosaurus
2013: Euoplocephalus in Egg→Dilophosaurus
2014: Mosasaur
2015: Tyrant King→Tripceratops
2016: Ceratosaurus
2017: Gastonia→???
(I don't include the repaint, bronze version and other dinosaur statues that are NOT belong to 'Sideshow Dinosauria')
It may not be fully correct, just for reference.
