This was also announced. There will be different versions. This is the super deluxe limited edition from Amy's website.
Bonus tracks :
The Wallmart Edition has an extra 2 live tracks.
This is ridiculous. The entire 'Heart In Motion' album and every released remix
easily fit on just two discs with a bit of space to spare.
Another great example of how frustratingly random these deluxe editions can be. "Just fill a CD with this incomplete assortment of tracks from that era. No need for basic research, or regard for logical sequencing".
Instead, they should be releasing:
1 - The remastered album plus the previously unreleased songs on the first disc (also released separately for casual listeners who just want the album remastered and a few "new" things to hear.)
2 - Two bonus discs with all of the remixes from 1991-1992. (Plenty of room for the live and demo recordings to go here or on the first disc)
3 - A DVD with the five music videos (plus alternate versions), and maybe an EPK or interview from the era.
