1) The screenshots showcased aspects of the game we hadn't seen before, giving a great new perspective on some game aspects, this was a definite high point of the release. Especially races!!! The Orc, I mean I've never played an Orsimer in a TES game before, but when they look like that, I may just have to.

2) The articles we got I actually loved. We may have only gotten a small amount of 'new' info, but the descriptions of the demo gave me a feel for what the game was like, something all the screenshots and info in the world could never do.
3) At this stage, I don't want Bethesda ruining the game for me, so I'm glad they didn't overdo it with what they released.
