It is Mick who still talks, actually posts about a new album. He was in LA in june for a "a great week recording" and last week he posted he was going to London to work on his album.
No hint about the release date, but if it is in 2027, as Lindsey's album apparently will be too though who knows, these guys will be active next year.
And I think this was a (last year) post where Lindsey is shown in a Mick's album recording session.

So two albums from these Mac people plus the 50 anniversary of Rumours, it could mean there will be performances, interviews, where they cross paths, appear together, etc. Good for them if that happens, I just hope they don't announce it as a reunion.
