Whether the category is "set up properly" or not means little since a general category for Apple Pippin currently does exist. Along those same lines, an entry's categorization is able to be freely updated at any point. Should the Apple Pippin sub-category be divided into smaller regional categories later on, then moving relevant entries is a simple task to complete. If you're wanting to create the entries, there isn't any reason to wait for any action to happen, should it happen at all. Also, bear in mind that not all sections have regional categories.
