No, you're certainly not. They could save themselves all the trouble of interviewing everyone and give us 5 minutess of gameplay in a new level and I think we'd all be more than satisfied.
That aside, still a neat video.
Yes they could do that but then they woudn't have the chance to tell us how great they made the game and just generally tease us with it
Sure they could do so while showing gameplay but whatever it looks like a great game
and BTW if we're "satisfied" I don't think we'd be following the developement of the game as much
