Game development can be tricky... it's hard to know how much they're deliberately keeping back that is fine and how much is genuinely not done. Sometimes you have big chunks of a polished game done very early on that you build up from, and sometimes you have quite a ropey looking game which you can't really show off for about 90% of the development and then it all comes together in the last few months.

So it's hard to draw any conclusions.

BTW I was reading above what you guys were thinking about the airship. It occurs to me if they did it in a X kinda way, it probably wouldn't be the hardest thing to add in somewhere. It was just a glorified fast travel hub there, and we already know they've got fast travel in the game.
