Thank you for mentioning this, the sole reason I registered on the forums was to like your comment and reply haha (even if its almost a month old). I asked a similar question on reddit, but people were pretty angry with me as a result.
This was my comment:
"I absolutely loved the trailer, but I was a bit bummed as a lore and story fan, since I felt like I was watching a huge spoiler. If these events are supposed to be big stepping stones for our character's development, I don't think the key moments for this arch should be shared as a trailer. I feel like I'm robbed of the future surprise and anticipation when I go through these events as I play (I think it might be the 'tutorial' origin story, but it's just a tip, I'm not sure).
Don't get me wrong I still can't wait to play it, and I'm madly in love with the guys at CDPR, but I just feel like they might have shared too much of a character defining 'quest line' packaged as a trailer. Even if its just a mere 'origin story', I would have loved to see how things will turn out without knowing what will happen.
What are your thoughts about this?"
I'm happy to find someone who also thinks it is an important spoiler.
