That's a little unfair. How was Bethesda supposed to market the game? "Skyrim is going to be amazing and you should definitely buy it, but we're not going to tell you anything about it because of spoilers ."
Well that's kind of my point. They have to balance marketing campaign with not giving too much away, but people don't consider what they release as spoilers. I don't blame them for that.
But can you honestly say it wouldn't have been more awesome to have not known?
Just comparing to some really minor details that are considered spoilers by some.
