Interesting that they chose to discuss the smuggler's trade and the Prowler at the same time, essentially begging the player to wonder whether they can get their ill gotten goods into the Prowler. It was NOT originally slated to carry any cargo. . .but. . .
Key note, at time index 4:35 he notes "this version" holds 20 plus 2 crew. Originally they said 16 marines plus crew. Still no big reveal what goes in that empty upper room, though they did mention "we're gonna have a lot of the components are going to be accessible in this space". I'm still hoping for an EW suite there!
