I was hoping for a closer look at metros but at least we got a bit of a look at the metro depot (I think, at 3:09).
I have to say I'm a little disappointed at the downgrade in airports, I really liked the modularity of the C:S I versions, but hopefully in time we'll get something more customisable (indeed with not just airports)
Yeah, it's more limited compared to the Airports DLC of C:S1. But I do like the scale better of them than the vanilla airport we got in C:S1!
The devs must know how much we liked the modular systems like Campus and Airports, so I think they're leaving those for future dlc's.
Same, also wanted to know if there will be hubs. I love using metro/train hubs in my cities. And I'm sad we haven't seen how we can upgrade train and metro stations.
At airports, we don't have updgrades for these, making them bigger?
