I am a radical, but I think a camera should be introduced with chart tests (resolution, moire, DR, and color), and an ISO ladder of the inside of the lens cap to show the noise floor. Some form of motion and visual load testing would be useful too to stress the codec and reveal any ghosting. Ideally these tests are carried out in a fully open, documented, reproducible manner by an independent test lab that knows how to do them properly. We then have an objective baseline for the camera system, and can move on to subjective concerns.
I think it's fine for there to be whizbang marketing pieces made, though ideally they aren't made by the gear reviewers (e.g. Philip Bloom being paid to make the GH3 promo and then casually leaving such conflicts out of his "ethics statement"). People want to get excited about their new toy. Certainly the C100 promo was embarrassing other than for those memorable girls on the beach and their lovely skin. The C300 promo was way over the top but announced Canon was now in town. These things cost a fortune to make and for a small struggling manufacturer are a luxury best left to the volunteer enthusiasts like you guys.
Though I honestly doubt anyone in this thread has ever shot footage in their entire lives that is as good as Reverie. I certainly haven't. But it's fair for you to criticize as it was made in the interest of separating you and your money. The people that bought 5D2s in 2009 after watching it still aren't suffering for their purchases however.
