The very first McCartney solo album came in April of 1970 ... way overdue for the "deluxe" job.  Serious fans should be aware in advance so they can work it into their budgets.  Release date:  June 14th.  Here is some info from the press release:

McCartney will be made available as a 2-disc (2 CD) Special Edition featuring the original remastered album plus seven bonus audio tracks including the previously unreleased outtakes “Suicide” and “Don’t Cry Baby” plus a rare live 1979 recording of “Maybe I’m Amazed”. For collectors, the reissue will also be made available as a lavishly packaged 3 disc (2 CD, 1 DVD) Deluxe Edition which includes an exclusive bonus DVD featuring rare and previously unseen footage, an extraordinary 128-page hard bound book containing many exclusive and unpublished photos by Paul and Linda McCartney, original album artwork, downloadable hi-res audio versions of the remastered album and bonus audio tracks, an illustrated history of the making of the album, and expanded track by track information for the two audio discs as well as detailed historical information on the film content.

More info is on Paul's very cool website.  Peace.
