Regarding the weapons, there are two different pistol-type weapons: the Luger-like weapon, which looks like more of a rapid-fire pistol, and the revolver, which is powerful enough to decapitate enemies in a single shot (which also means there's gore in Infinite, unlike in the two previous games). It also may or may not fire explosive rounds.

The Sky-Hook seems like it can do a lot of stuff besides moving around. It seems like jumping around with it doesn't deal you fall damage, and you can also target enemies while flying to dive-slam them.

Regarding the enemies, along with the ones mentioned there are a few other turret models, such as a machine gun turret at 1:07 and possibly a manned sniper turret at 0:53. As with Jack's Plasmids the Vigors visibly deteriorates his arms. Now, we know that there's a fire-based Vigor which likely functions in the same way as Incinerate! and that there's a Vigor named Devil's Kiss, but at this point we don't have enough evidence yet to affirm they're the same thing.

Among the locations there's also an aerodrome next to "Hotel Soldiers Field" which has the same look as a brothel-themed area we saw in a previous piece of concept art. This is likely a working-class/military barracks area. There seems to be an emphasis on Monument Island, which is probably where Elizabeth initially is.

The officer killing the other may be either an indication of the civil war in Columbia or the political machinations of its rulers.

The man with the coffin on his back had a Grim Reaper-like costume and a murder of crows on top of him. Whether this was Booker's doing or a power of his own is hard to tell.

Also, when the Handyman bodyslams Booker the latter gets an electric shock. Again, this may be either one of the Handyman's abilities or one of Booker's (new Static Discharge Nostrum?).

We can also see multiple factions in conflict, so sometimes not everyone's attacking you. Maybe this also means Booker can get allies.

I'll try to see if there's more to extract. Although it's not exactly as long or as informative as I expected it to be, it's still a goldmine.
