I'm not shocked to see the Museum will get new content. I felt like that was going to happen at some point anyway because it could only take a year to fill the whole museum if you manage to get everything before it disappears, and even then with the whole live updating system the game is going for it would be weird to not update the Museum when I expect Able Sisters and Nook's Cranny will both get new items to sell through future updates.

Bushes will be neat to add more foliage to the islands. Right now it's just flowers and trees although you do get bushes on your starter house, which now makes the idea of no bushes feel really weird. XD

I'm surprised Redd will use the secret beach and not the pier. It would make sense for him to dock at the pier because you know, that's where a boat would dock, but I guess if he's some black market dealer then the secret beach fits with the whole trying to not be open about it. Except for anyone who decides to set up houses and shops near the back of their island and dig away all the cliffs around that particular beach so everyone can see his boat just sitting there.

Cooking sounds neat but I don't really get what the point would be unless you can place the food items down, like if you baked a cake you could put it on the table or something.
