I would guess that they are trying to build some hype and hope that more people that are currently uninterested will get on the fence, if you will. Personally, I'm with Shady on camera options, but I would also like to see an in depth presentation of the combat and character(stats, talents, skills) system. I will admit that the interviews with people making the game are more charming than a cinematic that doesn't tell much about how the game will play, if only because they remind me of the PE updates.
