I really don't see them ever collecting the Power Girl issues in a JSA collection.   There isn't a big demand.  Yes, it is all winding down.  As the shift goes to digital, the two classic trades a month, five Showcases a year, zero Chronicles and possible Archive or two signal that what we buy doesn't matter that much.  Maybe a couple dozen copies sold of a collection when one or two sell at a store would affect sales with these low press runs, I don't know.

It's not at all like how moviegoers reacted to Man of Steel.  Whatever you heard did not affect Man of Steel at all.  There are so many more moviegoers beyond the niche comic fan, and movies aren't going away like comics may.  The same naysayers were probably the same few that went to GL, which tanked.  I like seeing old favorites represented with better printing and stories all in one place.  I can't think of anything the collections have done to turn me away.  Most store consumers aren't putting the books under microscopes like here.
