Who is replacing Robin Roberts on GMA?

Can you clarify for me who is stepping in to fill the shoes of Robin Roberts on Good Morning America? I'm eager to know the identity of the new anchor who will be taking over her role on the show. Is it someone we're already familiar with in the broadcasting world, or is it a fresh face that we'll be introduced to? I'm looking forward to hearing more about their background and what kind of energy they'll bring to the GMA team.
