I've said it before and I'll say it again:
The GameJam video is not the showcase of talent Todd would have us believe. It's a marketing tool designed to generate buzz and gauge the demand for various features. Features which were not created spur of the moment as Todd claims but were cut from the original game because they were not ready by the 11.11.11 release date.
So what's the point? What do you think, why did they show all these things to us? To get more customers to next DLC's?
At the end of the day, my opinion (which http://www.gamesas.com/topic/1400112-a-tad-disappointed-with/page__view__findpost__p__21318811a couple times) remains the same: "the more I play with Skyrim, the more I feel its shallowness".
I can't blame Bethesda for adapting to the environment where they get the majority of their money from. On the other hand, for the false promises and cheap tricks ...
