Cities Skylines 2 trailer speculation

This week, Colossal Order finally formally announced the anticipated Cities: Skylines 2 and released an official announcement trailer. Unfortunately, the trailer does not have any actual gameplay footage, nor are there any actual in-game screenshots available (that I know of). However, I do want to take some time to go through what is shown in the trailer and make some inferences about what may or may not be in the actual game. Even though the trailer is a pre-rendered cinematic, instead of actual gameplay, we can assume that what is shown in the trailer is intended to represent the actual content of the game -- at least on an abstract level.

First and foremost, here is the trailer itself, in its entirety. I recommend you watch it before reading on.

I will be breaking the trailer down based on 3 criteria. The first is what the narration says, which may provide some hints as to how the game will play. The second is what is actually shown in the trailer. The final category is things that are not included or implied by the trailer.
