The important thing right now is that the sets that are out already sell. If these sets don't sell, then it stands to reason that more will not follow.
That being said, I definitely would love a set like this TNG
one that covers DS9
, particularly episodes like "Our Man Bashir," "Badda-Bing-Badda-Bang," and the finale.
As for Enterprise
, another thing to remember is that there are several leaked scores already floating around on the internet. The more those things circulate (likewise the shameless bootlegs of the Ron Jones set
), the less likely we are to see new albums produced.
