The Landslide singer tells ABC News Radio that she and bandmates Mick Fleetwood, John MCVie and Lindsey Buckingham will regroup for rehearsals "somewhere around the end of February".
She says, "If everything goes to plan, we should probably be out (on tour) by end of April."
And one big gig that could be on the band's schedule next summer (13) is a first-time appearance at the Glastonbury festival in England.
Organiser Emily Eavis tells NME.com, "I think Fleetwood Mac would be amazing to get. We haven’t had any conversations with them yet but, you know, it is still early days. We’re just talking to some headliners now."
The band last hit the road together in 2009.
