The late rocker's official Instagram account just teased that they have some big news to share and folks will be finding out soon.
The Petty website also launched a countdown to the announcement, which appears to be coming on Friday.
Petty passed away in 2017 at the age of 66. An all-country Petty tribute album, Petty Country: A Country Music Celebration of Tom Petty, was released earlier this year.
