It does look weird having Big Bird's doors removed and Oscar's trash can moved from its original location after all these years. If they thought it was outdated for Oscar's trash can to be on crates and piles of trash, couldn't they have put the dumpster in its original area? But it could be worse - Oscar could have moved into a recycling bin, or into a plastic trash can, or worse, a plastic trash can with wheels.
I always felt that Big Bird's doors were to give him a bit of privacy, to make it more like a home. So I don't think Big Bird has ever been bothered by a lack of privacy, but at the same time, without those doors, he's pretty much just in a nest (I know, he still has his other things).
I wonder how many apartments are located at 123 Sesame Street. It looks small, but I've assumed it could house at least a few more residents than just Susan and Gordon, Maria and Luis, and Bert and Ernie. I think I used to think The Count lived in that building based on the fact that he sticks his head out the window in Sesame Street Special (not thinking that he could have just been visiting Susan and Gordon's home), and I also think I thought Herry lived there (I think I saw him stick his head out there in Sesame Street: 20 and Still Counting). So I see no problem with Elmo living there now.
I think somebody said that the street sign would have a change, but in that video, I didn't notice anything significant (it just looks a little smaller to me). But one thing I've been wondering for a long time: Is Sesame Street the only stree sign to have that thing above the street name that says "CTW"/"123"? Because I've never seen any other street signs like that. I believe I've sometimes seen big street signs, but most street signs are small and have the names of two different streets (the one you're on and the one you turn onto). Sesame Street is the only street sign like this that I've seen.
