The newer model of Dave is what he looks like in the show, so it's good they changed it to avoid "false advertising", despite the slightly awkward expression Dave's got. I guess they can always change the model again.
I personally hope they'll add some design features to his shirt because as of right now it's not appealing animation-wise, as it doesn't move very much and kinda seems more like a slab of fabric.Ā
Ā He actually looks kinda hunky. Like somebody should marry him now! Like probably a new neighbor, who has a crush on him.Ā
