So let me get this straight,because it's hard to comprehend.
After hunderds of forum topics with thousands of replies on them that appeared in the run of many years,developers decided to materialize them in their game,but not include them.
Yet they wanted us to know it,and they made a trailer video to show to us that they did everything we hoped for yet didn't see in the game.
What kind of cruel teasing is this ?!

Some of there where no brainers.Why not include them in the first place ?
Because they would become important and thus "steal the spotlight" ?
What a weak excuse!
Come on,that's the point.To give the player the option to decide what's important and what's not,that is supposed to be Bethesda's goal and motto "Be who you want,Do what you want".
I'm excited and annoyed at the same time.
This is exactly my position too. All of this stuff is amazing, and if the developers could individually have come up with this stuff in just one week, then it should have at least been considered for the main release. It's like Maiq the Liar's personality encapsulated in video form.
On the flipside, though, there's no way Bethesda would have teased us with this is there wasn't at least a good chance of some (if not all) of the content making it to the game at some point. That would be utterly appalling PR - "hey look! All this awesome stuff that's possible in the game! Yeah, you can't have it though." Clearly this was a calculated marketing ploy, and given how keen everyone (myself included) is to see this stuff included in the game, I'd say Bethesda probably have the answer they were after.
Whether it's paid or free is a different question. I don't think it should be paid - similar to the above point, Todd himself mentioned the possibility of it being a free update. It wouldn't be a popular move for him to backtrack on that now, although I can see it happening nonetheless.
