I had noticed that Rhino wasn't mentioned at all in the press release and articles about the upcoming remasters, and I believe they weren't mentioned in regards to 'The Very Best of Fleetwood Mac' either. That title was issued under the "Warner Strategic Marketing" banner, and I'll bet that the upcoming reissues will carry that tag as well.
Some of the Rhino guys (Bill Inglot, David McLees) were involved with the releases, but the Rhino name was never officially attached to the projects, it would seem.
Also, 'TVBoFM' was never available thru Rhino's main website, only thru
OnlyHitMusic.com, and the press release for the reissues stated that they too would be available thru OnlyHitMusic.com.
Anyway, what I'm trying to say is that I doubt this will affect any future Mac reissues negatively.
(Oh, and Cammie... 'Tusk' is already on the release schedule, so it's definitely coming out.)
