Ok, I'm calmer. Did not have a good day at work.
First, 2 more pics for a bit more details. One shows the troglodon's other head spitting acid.
My opinions:
For the model sculpts, I'm pretty underwhelmed with most of the models, in terms of the look and feel.
Troglodon - looks pretty good, although the acid spit is not my thing. With the carnosaur head on, though, it looks pretty weak for what it's meant to be. I personally much prefer the old carnosaur.
Ripperdactyls - I feel like they just phoned this one in. They wanted a different build for terradons, but had no clue how to do it. Unless there is something else aside from the head that is different, I'm not a fan (I would also like to remind everyone that they're going to have to use the term "ripperdactyl" when they play with, display to a friend, or discuss this model. Yeah...)
Terradons - it's hard to tell from the photos, but I think these might be better than the current sculpt. The riders are too blurry to decide on, but having more flying mount chief options is good for variety.
Bastiladon - do not like. There doesn't seem to be much detail in the model, but what breaks it is how static the pose is. Also, as someone else said, Pokemon will definitely be suing for copyright infringement.

Tetto'eko - it was always going to be hard to make this one a crowd pleaser, IMO. Personally, I think it's the paint job more than anything that a lot of people disliking this (those feathers...). This is a model that really needed a lot of character and detailing. And it may, because I don't think you can tell from these pictures.
Skink High Priest - ditto for the poor paint job. Could be good.
Gor-Rok - Ditto again for the paint job, but I think this one's a flop. From those angles, it looks like a pretty low effort conversion. No deal.
What's exciting for me is the potential for conversions. Almost everything is plastic, seemingly a lot of options = lots of bits, great for quickly making a unique army.
Carnosaurs for scar vets is great. You'll no longer have to choose between a carnosaur and a slann.
Given the variety of stuff that's just been dumped on us, there's potential for a diverse army build pool. You would assume the ripperdactyls will fill more of an assault role than the terradons, the bastiladons will hopefully give some buffs/hexes, skink magic will get a boost, a new magic lore for slanns, and just what role a troglodon will fill is unclear to me. If it's well balanced, it'll be great, you'll keep your opponents guessing. If not, army builds and gameplay will grossly favour one type.
I gues we'll just have to wait and see what the rulebook does to the current and new models.
Lastly, I'm pretty dirty that they didn't do a coatl

I think they knew we all had good alternative models
PS: those guys did not have the best grasp of what was going on. I wouldn't assume that thing actually launches snakes, or most of the other things they said.
