Stevie Nicks gave more information the Fleetwood Mac reunion while speaking to ABC News Radio.  The band will get to work in 2013.  Nicks says:

"We go into rehearsals somewhere around the end of February. So... if everything goes to plan, we should probably be out [on the road] by end of April [or] May, I would think."

Nicks also mentioned that the band plans on working on new music. That discussion will happen more once the members of the band actually get together, but multiple songs could be in the works.

Over the years, the band has endured breakups and personnel changes.  Key members of the current lineup are currently working on solo projects.
