You know Madonna has a whole album waiting to be released. Likely the first video as well. Cover art, first single art probably too. I fully think she was going to drop her album before her tour last summer but it obviously was postponed. I also think she was going to use the tour to promote the first single, we all know the ending of her show was supposed to be longer, most likely ending with her new single.
All speculation but it is what I've always felt.
