A robot of some kind patrols the tower area. If the Guardians are all human, and the only other robots mentioned so far are Vex, these may represent another force, perhaps direct agents of the Traveler who act to keep peace in safe zones, much like town guards in an MMORPG, or Concord in Eve Online.
Another scene that appears to be in-engine, if not in-game.
This is the first shot in the ViDoc, aside from perhaps some of the spacecraft scenes, that look more like in-game footage than just concept art, or renders of game assets against a blank background.
Presumably this is the tower area overlooking the city where Guardian characters will congregate.
We're building something alive. It has a nature that we don't totally control. Things are going to happen that we don't plan, and that's amazing.

A bold new action game, set in a living world
We're blazing a ton of new trails.
Bungie has generally preferred open plan or "war room" designs for their working spaces, and famously rebelled against Microsoft's cubicle culture shortly after the buyout. Desks are all on wheels, allowing for small teams to be configured and reconfigured quickly.
Some teams seem to be arranged around Destinations, such as the one in the center background with the Mars banner; others might be arranged around species, such as the one in the left foreground labeled "Vex".

"We needed something that challenges and inspires all of us, something, that I think, has enough ideas in it that it'll last us for the next ten years."

One game a year between 1992 and 1998. My, how times (and development cycles) have changed.
Bungie's outer lobby shows their company history, as well as more recent Destiny tricorn logo.
"Don't make us kick your ass" is written above the door in Latin.
If I had to guess... Hunter.
The heavy armor and big gun make this Guardian probably a Titan.
This Guardian's weapon almost seems like an archaic revolver, a stark contrast to the Cylon-like visor.
Another Guardian render, this one armed with another familiar-seeming sniper rifle.
Distinguishing between the three known player classes visually appears to be more complicated than simply examining available gear and equipment. All three classes appear able to carry and use guns, and wear helmets. All player characters are depicted having their faces concealed.
