"It's all about making announcements and revealing things... I'm sceptical about it, it won't be until next year anyway and I don't think they'll leave the other people sitting there for the next eight or nine weeks waiting for Karl to come back," Peter continued.
He added that Karl is already on the payroll for Nine as the host of This Time Next Year, and so he could easily move back to Today.
"The show, this year with the revamped version has not really taken off, it has stabilised. Not going up or going down," he said about the ratings of Today, which is currently hosted by Deborah Knight and Georgie Gardner.
And Peter said he suspects that Karl might go back to Today as a regular guest or roving reporter.
"I suspect it's probably Sunrise's worst fear if he does come back. It would create a bit of curiosity and traction there," he said.
Karl was sacked from his Today role in December 2018 after being the subject of controversy.
