One thing i noticed is that the colors seem closer to the pre-2023 colors rather than the 2023- colors, especially the purple. The music also doesn't sound too different from the current version but it sounds filtered and I'm wondering if the intention was to give it a sound similar to the actual physical chimes (I'm reminded particularly of the 1953 chimes)
The animation itself isn't that remarkable, we're back to a glass Peacock unfolding on a black background like '86 (albeit the animation is very different and i cant recall them doing this type of animation before except maybe during the Chime In era? But even that was different)...I can't tell if all these retroish ideas are purposeful, but given that the new Peacock font is a good bit similar to Futura (look at the Cs and K) I'd say this could be a purposeful, if lacking, callback
