Tweet doesn't appear to be showing up, but the 2019 addition is officially the return of the Antique Cars. I think it's a smart addition for the park, bringing back an old fan favorite family attraction in an area of the park that is literally dead (if I have the exact location right). Spruce up the area around it and bring on that Giga for 2020.
My only disappointment is that there was nothing announced about the Racer, but that could come later today.
