An update in People magazine states that the tour scheduled to begin in September, for which some dates were nearly sold out already, is still something that the survivors are looking at.
Without Naomi Judd, the tour evidently won't be what it was planned to be.
However, the update says that those who survive Naomi, such as her two daughters, are considering that fanbase of theirs who have already paid the price of admission, and have thus shown their support;
Wynonna, Ashley, et al. want to make some gesture of appreciation to the concertgoers and fans, and not simply shut it all down.

Which reminds me of an interview, not with Naomi Judd, but with Wynonna, talking about signing autographs for the fans, and responding with indignation,
not at the fans, but at colleagues who would not acknowledge fans:
"They should have their butts spanked!"
(Wonder who taught her that ... actually, I don't wonder.)
