No-t the first time we've seen people in trailers, and it turned out to be "just trailers" last time. Walking around has been promised to be a later expansion, and I see no reason to suspect that this has changed at this late stage. It might just be possible that we'll see more "live scenery" in stations with NPC's walking about, but given that this is already the part of the game that has the lowest frame rate I wouldn't bet on it. Besides, the landing deck is supposed to have 1/3 earth gravity so they wouldn't actually be walking normally like that... more like bouncing around.
