Maybe they are waiting for the sales of THIS ONE to gain some traction before rolling out another one...of course it's not surround...but I'm going to get it anyway...
I honestly don't think the release of that collection has anything to do with the release of the deluxe editions.
Many times releases like that one will come out in foreign territories and the artist will have no control over it.
Heck they may not even know it exists.
But regardless, it's great that Ferry himself is talking about the upcoming deluxe edition, as it's probably one of the most anticipated releases for me since I started on this crazy hobby about 7 years ago!
