That's cool, and I bet there are other people who feel the same, but I still feel like it's understandable why some people are annoyed by this.
What's there to be annoyed by?
Before the game came out, Bethesda said "Hey, we don't have anything to announce specifically about DLC yet, but we're going to sell the season pass at a lower price for early adopters", and they offered it at $30.
So it's a given some people bought it at that price, while others have waited to see what's included. Now that they're telling us the
first three items coming in the season pass (this is important, as it seems like a lot of people are missing that the content announced today is not the entirety of the season pass content) are, and that the "real" price of the season pass will be $50, but there's another couple weeks for early adopters.
If you didn't buy the pass yet, today's announcement means nothing to you, other than detailing a product that will be offered, and letting you know the price today is not the permanent price. Given that the $30 was always supposed to be a discounted price, this isn't new information, outside of the specific details.
The only legitimate complain here has nothing to do with the price, and everything do with whether or not you're happy about the what DLC they *are* making, and I can see how some might want more story DLC and fewer "features" that could/might be mods anyway.
