We haven’t actually talked about Zecora, primarily because we aren’t sure as to how many background ponies we will actually introduce. The Mane 6 will be seen for sure, along with Luna (obviously). The rest like Doctor Whooves, Lyra, Bonbon, etc. would probably not introduced until much much later. And by that I mean it is very unlikely unless the storyline moves into a direction in order to introduce them sooner.
The lack of TMI questions on TMI Tuesday is upsetting.
Anon, you are absolutely right.
