It's not impossible they would fit this one in somehow, but I think the chances would be very low if it didn't make it into what is probably a rainforest pack. If it's islands then of course that's still an open possibility. And of course, if they don't make in the game, it's not because the developers didn't hear us and see our need for them, I can only imagine it would be a matter of being so difficult to code and model that they just couldn't find a way to do it right.
Nonetheless, expecting that it will make in it if it's a rainforest pack and as the headliner animal, will be gracing a video reveal either Thursday or Friday morning!
