I'm thinking yoshida means something like how he plans to add a gold saucer like area to the game. Most likely not an exact replica. Think about the Job AF gear as well. It's not an exact replica of another FF game's iconic view of the given job but it resembles it and has similar elements to it.

Think about it like going to disney land and then going to disney world. It's not exactly the same but it feels familiar (except the castle).
