This reminds me of those contests that radio and television stations run where they announce a secret word or number at different times so you have to listen and/or watch the whole thing lest you miss one of them.
Nice try, ABC. After each announcement, that person will be posted on abc.com, so I'll just check the list later that night. Or just watch GMA on Monday morning.
The only person that has confirmed that they are on the show so far is
Spoiler
Donny Osmond.
