It's been leaked the Major Spice Girls reunion will include all 5 Spice Girls... kind of...
The album promotion will include all 5 Spice Girls going to various interviews separately, promoting the album as well as whatever individual project each is working on.
The album will be released ahead of a mini tour which (as of now) will include 4 Spice Girls, not including Victoria Beckham. The album will start as 5 tour dates and they are hoping the buzz will expand the tour as it did their last time. 2007/2008 RETURN TOUR.
It's expected the tour (described as 'mini') won't last more than 2 months as Melanie C. has an album she is likely to release toward the end of their tours. (Smart Spice? Selling her solo albums at tours is maybe the best idea she could have).
The Greatest hits re-release is planned to be named "20th Anniversary: The Hits" Below are the details for each disc. The deluxe package includes 6 Discs.
