Former Emmerdale boss Blackburn took office at the Weatherfield soap at the beginning of the year, succeeding Phil Collinson. He is expected to be credited as producer from Monday, April 8.
In a new interview with TV Times, Blackburn discussed a number of future storylines, including Hayley's upcoming exit and the huge fire on the way at the Rovers Return.
Asked whether Hayley will be killed off, Blackburn replied: "We're a long way off that storyline. Obviously Roy and Hayley are now going to be central to the show for the next 10 or 11 months. All I can say is that we're working on the most beautiful, moving story we can find."
Discussing other planned storylines, he continued: "There's a long way to go for Stella, Karl and the pub - we've got some really strong, powerful stuff coming up for them. And keep your eye on David and Kylie - I love that young couple and their relationship with the rest of their family.
"There's a big storyline ahead for Peter and Carla, we're going to be moving them on apace. Tracy's been relatively quiet of late - she'll come back to the fore."
Teasing the aftermath of the fire, Blackburn promised that the look of The Rovers will not change and that "rumours it's going to get bigger and become a B&B are nonsense".
He added: "The story at the moment is that Stella is the landlady, and when the pub's burnt down, we'll see her battle to get it back to where it was."
Blackburn also said that there are no immediate plans to introduce new families to Weatherfield, as he will be concentrating on making sure existing characters are working "as best they can".
On his vision for the show, he commented: "It's about going back to basics, to the very first episode of Corrie in 1960. Right from the start, it was witty and warm but it wasn't nostalgic, it wasn't whimsical, it was an act of rebellion.
"It was the first time a popular TV drama had tackled the lives and loves of the working classes. That, for me, is what Coronation Street is, and what I want it to be while I'm here - 21st century stories about real, believable working class people."
Coronation Street continues on Wednesday (February 27) at 7.30pm on ITV.
