Regarding implementation in the parks...
As
@Alicia said, a lot is mostly for marketing, banners, brochures, etc; but I really do think we may see the lighthouse emblem get an updated look. USF and VB got "updated tweaks" where they can leave stuff as is but IOA was a pretty big change. It wouldn't shock me if that is the plan. Maybe not an exact copy, but something along the lines of the new direction.
