Eh, it depends entirely on the models/designs they come up with. If they play their cards right, they could get some impressive rigs and animation.
As someone that liked the Disney Fairies franchise and Sofia The First, I’m curious as to what they can come up with.
They might go for a RID cellshaded style. Maybe they’ll work some serious shader support and actually render fur. I wouldn’t even be opposed to the style of the simple models used in youtube. Some can work magic with those. It could go in many directions.
Also, there’s no guarrantee it will end up 3D. They are barely in the concept art stage.
