I think we all need to take a deep breath. A lot of people have the same concern including me, but remember that this game is going to receive free updates. If it's not in the game now, they're most likely going to add it in a future update. They probably don't want people time traveling to unlock things like Brewster and other shops right away, so they could be locking them behind free content updates. I also heard there are some things that reviewers aren't allowed to show or talk about, though I'm not 100% sure about that. There's no way they're going to reveal the entire game before it's released.
We'll just have to see! I'm sure the game is going to be fantastic.
I think we all need to try and think about everything positive that's been shown in the game so far, instead of worrying about potential negatives. We're close to only 3 more days now.
