"I feel a lot of pressure because I hold myself to pretty high standards, and I want to have a smart conversation about a whole variety of topics," she said. "To put those kinds of demands on yourself, of course you feel pressure. On the other hand, I'm also really excited."
But Katie is also pretty secretive about what's she got planned.
"We haven't said all the guests we're going to have on and all the topics we're going to tackle for competitive reasons, you know? We don't want to see them everywhere," she said.
She did reveal that she will have a studio audience of 144 people every day and that each show will generally cover one or two topics. She also said social media will also be a big part of the show.
Katie and her crew have been working on this show now for more than a year, planning, creating and having fun.
"I think it's a great situation. We have a fantastic team and we work really well together," she said.
As the clock ticks down to this new chapter in Katie's career, she is simply thankful.
"I just feel like, 'What a wonderful opportunity I've been given,'" she said. "It's a real gift, and I just hope that I handle it with care and do the best job I possibly can."
"Katie" debuts on Monday, Sept.10 at 3 p.m. on ABC7.
